anxiety and stress
"I'm currently taking Prozac (Fluoxetine) for severe generalised anxiety disorder, social anxiety and panic attacks.  I only take 20mg a day and even though the first month left me with horrendous nausea and weight loss it subsided after about 25 days and now I find that my appetite as a whole has decreased slightly but the nausea has now subsided.

My anxiety has improved so much to the point that I'm actually leaving the house for activities other than work and I'm having conversations with people I'd usually ignore because I'd feel so self conscious. I've actually had people (that don't know I suffer from anxiety or that I'm taking Prozac (fluoxetine)) comment on how well I look recently and how happy I appear within myself."
