I was on adderal at one time and it was making me manic, My doctor said the same thing it could be used instead of a A.D. I went into the hospital one time impatient and the doctor told me that adderal is just like taking crystal meth, I don't think you should mess with that personally, I would just stick to coffee, They also have drugs for ADHD that will not give you the stimulant effect, I hate being manic because when I get that way I go off the deep end, Please drink coffee and good luck
