The thing to keep in mind about stimulants like Adderall is that you build a tolerance to them rather quickly. So if you're popping them everyday, you'll need more and more to get the same end result. This is why people that actually take them daily tend to have to increase their dose to 40-80mg just to get by.

Also keep in mind, that you will be tired when you stop. If you're using it for a couple of days, expect the following day off to be a slow day. If you're using large doses for a long period of time, withdrawal symptoms can last a couple of weeks (fatigue).

Don't take too much caffeine with it unless you want a strange "overstimulated," zombie like feeling.

I use it at most, two times a week but ONLY when I have a list of things to do already written in front of me. I can't stress that enough. If you're going to use them to increase productivity, have a to-do list ready otherwise you might end up wasting your day focused on something completely unrelated.
