Yeah can be tough depending on the med. I’m not sure how long as we are all different but I’d think a week or so will be better. Most meds are absorbed pretty quickly and leave just as fast.
I’d visit a gp just to see that it’s not doing something to your blood pressure just to be on the safe side. They should have up to date info on the meds too these days. My gp has all my records and knows more about meds than me for sure.
Taking sertraline gave me massive headaches to begin with. I was only on it for about 4 months. I think it took 2 or 3 weeks for the headaches to subside on the withdrawal. Good luck.
