I've been buying prescription adderall for a while but wanted to try SuperSpeedBros amphetamine sulfate because I'm broke don't want to spend $5 a pill.
My dosage for SSB's speed has been about 30-40mg. I feel good for about an hour then I start to develop intense headaches and it becomes impossible to study. I used to take 20mg adderall xr and never had this problem. Has anyone had a similar experience switching to amphetamine sulfate?
Could this be due to purity or some other factor? I thought it was due to me having too much caffeine but I stopped drinking coffee and I'm still having this problem.
Staying hydrated? That's my only guess. Love his stuff but I usually down a gallon and a half of water a day
