Health - Stomach problems on adderall

[gilligan_911]

so swim is somewhat experienced with amphs, ie speed, ritalin, and adderall. he has used them and had no real problems but recently swim has been having an increasingly upset stomach when taking addies. around +1.5 swims stomach becomes a violent bag of noises and gurgles and general discomfort. he's only been dosing around 20-60mg and with low doses the effects are minimal and as the dose increases so does the negative effects. swim understands a bit about amph salts affecting the GI tract but has anyone else experienced these sort of issues? and if so, what did swiy do about them?
