I have found it challenging to find many long term buprpion users, but virtually all the ones I've spoken to seem to need to increase their dose after 1-4 years of use.

I know- I'm only 7 weeks in and this is not a problem I should worry about yet. But... at 300xl, I'm hoping I will be good at this dose for life or need less!

Does anyone find they need to go DOWN in dose with time?

Is bupropion a drug that loses its efficacy over a period of time?
