Coming off Sertraline, starting propranolol, feeling weird!

Hi, I was just wondering if anyone would be able to advise me please if anyone has experienced the same?

I have been on 50mg Sertraline for a couple of years and decided to try coming off them as not sure if they do a lot for me. I had been reducing them over the last couple of months but have been struggling with feeling anxious, mood swings, tiredness and migraines every other day (I am a migraine sufferer anyway). I spoke to the doctor last week and she suggested I try taking 40mg Propranolol 3 times a day for next couple weeks to see if this helps me to feel better. I took one on Sunday, felt fine other than quite tired, took another one on Monday with the intention of increasing to 3 x per day as prescribed but felt really odd all day. I have continued with 1 per day but feel weird all the time! I’m too scared to take more than 1 at the moment. I feel quite lightheaded if i move too quick, the bottom of my feet are tingly a lot and I have awful tinnitus. I did have tinnitus previously but now its more like a radio signal kinda noise when you try to change radio channels if that makes sense? I stopped the sertraline when i started the propranolol (had been on 25mg every other day) so now I’m wondering if these effects are from the propranolol or if they are from completely stopping the sertraline? On the plus side I haven’t had a migraine so far this week! I did take propranolol years ago for social anxiety just as and when needed and didn’t have this, but then I hadn’t been on sertraline before either.

Has anyone else been through similar on these drugs? Thank you.
