ADHD
"I have tried a variety of medications for ADD; including Ritalin, Adderall, Adderall XR, Dexedrine, and Strattera. Each has benefits along with side effects. 

After several years medicating with central nervous system stimulants (CNS) I  switched to Strattera. I found the medication took a few weeks to take effect, and tended to cause constipation. I also found my psychological state was less effective if I became dehydrated. 

To counter the side effects I added All-Bran into my diet twice a week, and drank more liquids. The big benefit for myself was I could enjoy reading books again, which I could not on the CNS stimulants."
