I take 30 mg in the am and 30mg @ 2 pm, I just started working, roofing. I've been experiencing heat strokes everyday. Would Adderall have any effect on that? or is it just the heat, everyone else can seem to stand it. It's been 97 degrees with 107 heat index. I'm used to working outside on roofs and haven't experienced problems like I have: breathing, dizziness, and stomache sickness.
