Definitely talk to your doc. (My GP prescribes my meds; the psychologist diagnosed and wrote a letter).
I don’t really have noticeable side effects. When I first tried the stuff I started at 30mg then at 40mg I started seeing lots of bright spots and went back to 30. Freaky experience.
I’ve been on 30mg for years now. My heart doesn’t usually race but some days I get a little jittery. I don’t recall it being elevated back when I was using an exercise monitor. It probably doesn’t help that I drink a double shot latte every morning with my meds. My BP did not seem to be affected by the lisdex last time I tested it on and off the ADHD meds. (I am on BP meds too).
Worth mentioning, I am also on Effexor (venlafaxine) for depression and anxiety, which was diagnosed a decade before adhd-c. Prior to Effexor I was on Lexapro for a few years.
When I was testing dosage, my PA said to increase 10mg every few days until I noticed it helping, then increase until I noticed side effects and then we would go with 10mg below that. Or something like that. Which is how I ended up at 30mg.
I recall that I couldn’t tell at first how much 30 helped vs 40 but now that I have more experience with the medicine and self evaluating my symptoms. The difference between 30mg and none is now very obvious.
Although… I have been thinking about trying 40 again so I can re-evaluate, in case I get a bit more out of it without side effects this time. Maybe I will do that next time I’m up for a refill.

Call your doctor.
Thank you for your input. I’ve updated my original post with the reason I haven’t done so yet.
Contact your GP, they should get you an appointment soon.
If they can’t call 111. 111 may be able to get you an appointment for an ECG from a hospital or urgent care. Or some other intervention.
NHS inform is a much better place to get information than an internet form. It’s probably the best place for medical advice on the internet for non-medical professionals. It also tells you appropriate actions for your symptoms - treat at home, speak to pharmacist, call GP, call 111, call 999.

Honestly you should talk with your doctor about it. Even if random fellas in internet tell you it’s/it’s not fine, discuss with a professional.
Taking medical advice from the internet can be meh at best, extremely dangerous at worst
That said, I remember having only extreme moodswitches as side-effect when starting on concerta when I was a kid. Took maybe couple weeks to “stabilize” (or I got used to it)

I can’t say for lisdexamphetamine itself, but with plain old methylphenidate (ritalin) I found everything was really quite quick to adapt. I take Concerta 18+27mg in the morning and Ritalin 20mg on afternoons when I need it, so a total of 65mg in a day. When I started I had no real side effects but I did have a whole bunch of trauma based issues because here, finally, was the cause of many of my problems and my parents had lied to me about my diagnosis for 13 years. That said, my psychiatrist was gradually increasing my dose and when we tried the 54mg Concerta and the 25mg Ritalin I knew on dose 1 of each I was over my limit. Sweating, rushing, agitation, and generally feeling awful, it was too high a dose.
That all said, completely unrelated to my meds I had a heart infection last year. A bacteria (streptoccocus sanguinis for the curious) ate a valve and my first symptom was a chest infection. I had fever for a couple of weeks, some gout symptoms, coughing, sweating, and eventually I had to drive to the emergency room. It took me 3 rest stops to walk the 100m from my car to the emergency room and I knew I was in trouble. They thought it may be Covid but no, I had bilateral pneumonia and when the doctor listened they thought I must have a bicuspid valve. It turned out most of the valve was eaten away and the little bits of valve left were flapping away, sounding like a bicuspid valve. Further scans figured out the issue and I had an emergency flight from my country town to a larger city to get an emergency valve replacement. Two days after surgery I was up and walking again with a lovely new scar and a prescription for warfarin and a beta blocker. So if you are feeling weirdness with your heart it is probably a good idea to get it checked if you can manage it. I am in Australia so none of that cost me a single dollar, but where you are it may be different.
Thanks for the detailed response. I’m sorry to hear you had to go through something so traumatic.
Nah, it was honestly a really cool experience. It was scary at times, yeah, but I absolutely love medical sciences and it was a fascinating experience. I had world class healthcare with experts and overall fantastic facilities and now I have made a really good recovery. Most people with two collapsed lungs and a sternotomy (I think that is the correct term for open heart surgery) have long term damage, but I work an intense physical job and feel better than I did for at least a few months, maybe a couple of years, before it all happened. Now I have to take some extra meds on an ongoing basis but as a bonus I sound like a cartoon bomb about to go off. Also my partner can hear my heart ticking from the other room, so that’s pretty cool.

I am currently on vyvanse myself, originally 40mg down to 20mg (at my request, was lasting too long affecting sleep). Something I’ve noticed about it in particular is making sure to eat and avoiding caffeine. I get the jitters and heart racing if I don’t eat enough, vyvanse also decreases my appetite a bunch and makes me thirsty (I suggest water as the drink of choice).
This is only anecdotal experience, I also talked to my doc about it and it is being monitored. so as others also suggested, talk to your doc about it too, it’s more important and cheaper long term to get it correct and handled now than not.
