I started taking Vyvanse 30mgs a while back because of irritability issues from Adderall XR. For the first 3 months, I loved it. I didnt feel the need to take caffeine. After three months though, my subscription was increased to 40 mgs then to 50 mgs. I started to feel extreme irritability at this point in time but i was also going to the gym and taking caffeine supplements.
I know the caffeine might have caused problems but my question is has anyone had any side effects they know of from going to the gym and being on the medication?
If you were doing well, why was your dosage increased? A higher dose is more likely to cause side effects. And caffeine has a similar effect on the body, so taking Vyvanse and caffeine might not be the best plan.
