Sertraline
"I was prescribed this for anxiety and depression and can honestly say I wish I had never taken the first pill. I was told to take 50mg a day and after the first one I felt unwell with huge pupils and 'out of it' but thought I'd need to get used to the pill. After the second dose it was hell, no appetite, being sick, unable to keep anything down, a pounding headache that wouldn't stop, blurry vision, hot sweats, waking up every hour in the night, shaking and horrid thoughts. I contacted a pharmacist friend who said I had obviously got the worse end of the side effects and if I continued it might get better or stop and ride out what I was already feeling. I chose to stop, I thought this pill would solve my problem- it did not."
