Hi
@aidil I just wrote a huge message to you then accidentally clicked an ad. Haha
Late summer I started on 50mg and stayed on that for 3 months. Unlike you I found the mental noise lessened but the physical side effects actual got worse temporarily. Racing heart upon waking and randomly through the day. I didn't want to increase my dose because I was being stubborn and stupid. I went up to 100mg and stayed on that for a month. It didn't change anything so I was upped to 150mg. On day 12 I began to experience tremors so my GP put me back to 100mg with a view to bringing me off the medicine altogether. It turns out the tremors are not related to Sertraline at all. I've been dealing with physical health issues, (it doesn't rain but it pours), and my rheumatologist is confident that tremors and muscle spasms are associated with that and not Sertraline.
I think I need to go up to 150mg again and give it longer now I know it wasn't what caused my tremors.
In my experience 3 weeks has never been long enough on any medicine I've taken to gauge if it will be "the one". (I've taken various medicines for mental illness since I was 15 and I'm now 35).
Best of luck to you
