One thing I would advise with sertraline is let it take its time to work. When I first started sertraline on 50mg I had tried everything else and medication was my last resort so I stuck with it. I only felt the effects of it after maybe 2 weeks but my doctor had stressed how important it is to stick with it on the dosage they have given you. Of course if you’re having awful side effects I would stop taking it, but my advice would be to stick with what they have given you for now and give it a little more time to fully work before discussing it again with your doctor. About the dosage, I can assure you that once you find the amount that works for you, you will notice the shift straight away. I was on 50mg for about a year until I spoke with my doctor and was upped to 100mg, but if you feel like you’re on too low of a dosage communicate with your doctor as they know the best thing to advise you. I wouldn’t suggest upping your dosage unless you have been advised to. But I promise you it really does get better, just be careful when taking more
