Just to echo all of the above, I've been on sertraline for probably 6 years now. Before that I was on citalopram for a couple of years. Sertraline definitely works better for me. Not really had any bad side effects from it. I've tried to come off it a couple of times but like someone said above, after about 3-4 months I was getting really low so went back on it (though this was during lockdown so maybe not the best of times to try it!).
But all in all, it's definitely benefited me. I'm on a half dose I think which is 100mg
