Memory loss and fatigue with Mirtazapine and Sertraline, does anybody else get this?

Hi, Ive been taking Mirtazapine 30mg and Propanolol 40mg for years, I recently changed to Sertraline 20mg instead of propanolol while still talking my mertazpine 6 weeks ago because I got diagnosed with reyanuds disease. Over the past year Ive noticed a huge decline in my memory and its a bit muggy. My eyesight reaction can be a little slow too, and take a split second to readjust, while sometimes its just ever so slightly blurry.
I was wondering if anyone else has these symptoms? And if after all this time, if they are the cause I should try to come off them

mirt is terrible for eyesight, ive come off it 3 times xx

do you get any other symptoms ?? knumb hands at night ? reflux ?

Like said, got diagnosed with reynards so me fingers and feet and usually cold

We;; like I said, got diagnosed with reyauds and that does cause cold/ feet

propranolol makes your hands and feet cold its a side effect xx

How long have you been taking them?

4 years, 3 years then 10 days, my eyesight returned to normal once off xx

I know, hence why I stopped taking them and started sertraline for my anxiety xx

Did you get unfocused vision? x

yes x
