How do you decide on your breaks? I have prescription too, but I usually use everything up within 70% of the time period and then 30% I have a break, which was not intended, but this is what I've been doing anyway. In a way it's good to have these breaks at least to understand dependence and tolerance.

So each month I have a period of a little over a week of break.

I didn't say the break was intentional :). I run out, but I figured I'll just wait until the next appointment and see how I take a prolonged break, because it's been years since I did a break longer than a day. The problem is, as a father of two small kids, my family life and professional life are in fierce competition for my mental faculties, so I never feel like I can "afford" a break. I do recognize it's an irrational and self-defeating thought, but if that realization could impact my behavior, I wouldn't be on stimulants in the first place ¯\_(ツ)_/¯.

RE my break, I maybe had only a day of "withdrawal" that was more of a little panic mode, that lasted until I realized I'm really managing just fine, only maybe slightly less so. Week later, I was still managing fine - though everything was noticeably harder, and I was only compensating with habits developed since starting the treatment (and perhaps novelty of such long break itself).
