Sertraline
"I've been taking Zoloft for 6 months now...began at 25mg. and worked up to 75 mg.  I'm a person who hates being on medicines, so I tapered off to 50 mg and then tried to go back down to 25 mg.  Unfortunately the symptoms came back, racing pulse and anxiety.  I'm now back at 50 mg and feel even keel.  It has been humbling for me to admit that I need this medication and I dislike how it makes you feel dependent on it, but I also realize it is doing its job.  I have lost 5-10 pounds since starting it.  The first few weeks I was in a fog and suffered horrible headaches and nausea, but per my doctor's words those symptoms did subside.  I've not had a single panic attack since starting Zoloft.  "
