I doubled it myself. I got caught by the end of period at university and didn't have time to see my doctor. Not good, but it worked! I'm seeing him in couple of days and hope I don't get scolded...

I'm taking 20mg of paroxetine, which is far from high. I experienced hunger pains during adjustment phases, but once it settles I actually get less food cravings, especially sugar cravings. I'll keep that advice in mind though. Paroxetine messes up with my libido, so I'd rather add another antidepressant instead of raising it to high doses.
