Hi there, I am new to mums net, although often read posts and I'm looking for a bit of advice. I was previously on Sertraline 4 years ago for GAD/OCD, it worked wonders for 3 years so I stopped taking it thinking I could do without, 6 months later I crashed. So restarted the med and was on 50mg for 4 weeks after the usual side effects things started to get better around 4 week mark, then I had a blip so increased to 100mg and again was feeling much better for a couple of weeks, then again went downhill so increased to 125mg for another 4 week and again felt much better but yep you can guessed I have now gone back downhill again.... So I have now increased up to 150mg as of Saturday and I'm getting increased anxiety, which I'm hoping are just side effects of the increased dosage. Has anyone else experienced this before getting to their therapeutic dose?? I don't remeber it taking so long to work the last time
