I take Adderall XR on days that I work, and soon for days that I'll have classes or be helping with homeschooling. You have to do a lot of micromanage with yourself, making sure you get enough water and take vitamins. I have cramping in my hands, legs, and sometimes along my rib cage if I take it without doing those things.

Ritalin just required me to take it too many times a day when I was working full-time, and just wasn't as effective. The halflife is shorter do it poops out earler.

How much were you taking? Did you notice negative effects at all?
