Simplydivine, I am glad to read that you are feeling very good right now. Of course you don't really want to become any level of manic, though. What I hope for you is happy stability. I can't know if/when you may be hypomanic, but I suggest you contact your psychiatrist, quickly, to let her/him know how you are feeling. They may be best at gauging your mood state. They may even wish to adjust your dose so that you have long-lasting wellness, and not the start of something concerning. I agree with BethRags that 300 mg would be an aggressive starting dose on Wellbutrin. I agree with you that one week for it to make a huge difference is quick, though definitely not unheard of. If by chance your dose is eventually decreased, it can always be increased again, if depression symptoms return.

Do you live with someone who knows that you have bipolar disorder? It can be helpful when those near you clue you in when stable happy turns into something outside the norm, in terms of your behavior. Also, logging experiences during the day, and then reviewing them at night, can sometimes be telling.
