I've been on sertraline for 5 days now and its causing a lot of issues

- gut pain
- bed ridden most of the day (not sleeping) and sleeping too lightly in the night, maybe 5 hours tops
- I'm more able to do weight training and my chess rating has gone up, but I'm totally trashed and non functional with zero organisational skills

I was expecting the drug to take some time, but is this normal - i.e. should I stick it out or switch before I get hooked ?

This isn't for anxiety, its for pain management, and to stop my body going nuts about other health issues. I'm left wondering if this is the right drug !

I will of course talk with a doctor but I would love to hear other peoples experiences and views.
