anxiety and stress
"Did some yawning in the first week and then my libido started to diminish. After two weeks my yawning went away and was replaced with clarity and a clear mind. The unfortunate downside at 20 mg after two weeks was absolute zero libido, I couldn't have an erection. It's too bad because it's a very effective medicine otherwise. I've switched to Wellbutrin, haven't started it, going through a one-week wash off Celexa."
