Hi everyone, I've been taking sertraline for 9 years 50mg, it's worked great and felt so much better on it, but the last 12 months I've slowly crept back into depression mainly due to family illnesses and also my own health worry's. The doctor increased it to 100mg 2 weeks ago, I felt horrendous at first then the calm came after about 10 days, now the last 3 days I'm a mess again, is this normal? Do I need a higher dose or will it eventually get better again? Any experience is appreciated x
