major depressive disorde
"For this is the reason I most commonly check out medication on this site, I will refer to the time it took for bupropion to work:



To my surprise it took exactly 18 days. The thing I found quite striking is that on the eighteenth day it started having a huge effect within just a few hours in the morning. There after it kept working till today.

For me it was quite easy to deal with them. I had headache once in a while, but could treat it with aspirin and I did not sleep so well for a few days. Dry mouth is what stayed the longest but that seems pretty accetable compared with depression."
