I had trouble remembering if and when I took some pills

I am taking pain pills because I recently had knee surgery. For some reason this morning, I don’t remember whether I took both of the pills for my acid reflux, before I ate and if I took the pain pill with my other pills.

I’m going to just have to assume that I took the right pills, but because I have problems with my short-term memory, I’m just not sure. I don’t think that I will take a pain pill until lunch because I don’t want to take too many. Oh, the frustration, when I just can’t remember something that happened moments earlier!! I am going to take a piece of scrap paper and write down each time I take my pain medicines. That is probably the only way that I am going to be able to keep track of when I take it.
