That's in my opinion the best thing you can do - it always lasts a while until you have the right med and the right dose - but if you really suffering, then take it as prescribed. You will be surprised how much easier some things are, and already this is a reason for me not to abuse them. And you know, we ADHD-people need a bit more to overdose because of our fucked dopamine-system. It's not worth it, because if you have to do something and there are no meds anymore you will bite your own ass.
