100 mg too strong?
 

I took my first Sertraline 100mg yesterday. Since then my jaw is sore & tight, I feel sick & I didn't sleep a wink as lay there feeling so tired but on edge. Does the insomnia subside as having no sleep will affect my daily work & mood. Is it ok to take something with nytol at the same time?
I am more concerned that I have never been prescribed anything like this before & wondered if 100mg was maybe a bit strong?
I would really appreciate your feedback as I have had to come home from attempting to go to work as feel dreadful.
Many thanks!
