Nortriptyline and short-term memory loss

I have been taking 20 mg of nortriptyline for a little over one year now and I’ve noticed a short-term memory loss problem for the last 2 weeks. Has anyone else noticed this side effect? And if so, did you wean yourself off and how did you do that?

how is the nortriptiline working for you? I would think the memory loss would start pretty soon after starting the med- maybe it’s not related?
