I've been on Wellbutrin 300mg over over four years now. My psychiatrist increased my dose to 450mg (basically 3 150mg tablets in morning). The increase was because lately most of my struggles have been more symptoms related to dopamine deficiency such as lack of motivation, not getting a lot of pleasure put of things and focus/attention problems which is also part of my ADD (and being treated with Focalin).

I just had a little concern since I am going over what is typically the maximum (300mg dose)
