I was put on sertraline in 1997 for PND. And my docs forgot me and I stayed on it at 100mg. Back then I have no recollection of side effects at all.
BUT I decided to come off in 2010 with the GPs agreement, I took 9 months, but ultimately I ended up a very anxious wreck and after 6 months had to go back on. I stayed at 75mg this time. I am considered hooked and told not to try again.
I will say going on it the second time was dreadful and took months to get to normal, I had nausea, more anxiety, loss of appetite, lost my sleep pattern. These did pass but were horrid. Sertraline or any AD is a big decision, one I would not do if I had my time again.
