Hi, I'm a 45 year male, that has been on antidepressants since I was 15 years old. Lately (over the lasts 6 months) I have been experiencing, extreme loss of short term memory. I'll be watching a tv show, it goes to commercial and I have absolutely no idea what program I was watching. When, say doing some bookkeeping, I will look at an invoice, and when I go to input the invoice # or what ever I have to go back to the invoice, sometimes 2 to 4 times...
