I have am a 20 year old male and have been diagnosed with ADHD and was prescribed 10 mg adderoll. Nothing happened the first day I took it but the next day after feeling completely fine all day right in the middle of the day I bent over and as soon as I did almost threw up if I hadn t swallowed it back down ever since then which was about 3 days ago I have had what feels like a lot of pressure in my stomach. The pain isn t as bad in the morning but gets worse throughout the day. The pain that I feel is comparable to hunger pains but I have eaten regularly everyday. could this be a possible side effect or is it probably something different that coincidentally occurred right after I started taking adderoll.ha
