The beginning of sertraline is TOUGH. I'm into the pill scene and so on and the closest I could describe the first couple of weeks was constantly feeling like I was rushing on ecstasy. Teeth constantly chattering, nausea all the time and really on edge constantly. I cut the dosage down to 50mg again and it settled eventually and I did start to feel more at ease. My friend started on 50 and was floored and vomiting constantly for days and she was too anxious to see anyone for over a week. I'm not sure what I would recommend. We both had a horrid time starting off but eventually settled in bit I think if you feel you have to speak to a doctor then go ahead.
