I am on 100mg of sertraline for OCD, anxiety & depression. I started on 50mg and then the doc upped my dose to 100mg. have been on it 3 weeks now. I can handle feeling sick and dodgy tummy but I cant stop grindin my teeth which is so annoying and giving me bad headaches. Has anyone else had a similar problem? I dont want to swap meds yet as these are meant to be really good for OCD. I was previously on Prozac but made my anxiety worse! Please help!
