I havent messed with any of those pills yet, though I have two ritalin that my adhd friend gave me to try last saturday. Im not sure what they'd do to me. I used to take my friends lexipros, took like...4 or 5 at once or something. I dont do that anymore though, I felt like an asthmatic (sp?) cuz I couldnt breathe, dont know exactly what dosage I took.
