I don't know much about meds because I've been on so few for so short a time, but I do know it can be dangerous to stop/start meds. I know Lamictle for an example is very bad to stop and start suddenly because it has some killer side effects. And when you start or re-start you have to taper up, for the same reason

Some types of meds also cause horrible, horrible withdrawls.

Just be very careful.
