I don't know very much about
Ritalin, but I know
Adderall contains
amphetamine-dextroamphetamine salts whose chemical structures are similar to
methamphetamine, which is notorious for hair loss, weight loss, insomnia, restlessness, tremors, irritability, anxiousness, and even teeth loss at high doses. It's a very damaging chemical to expose your body to for several years, no matter what a doctor prescribes. A resourceful doctor will not prescribe Adderall for that long to anyone. It's some dangerous substance.
Jesus Christ will help you through. -Betsy
