depression
"I have been on Elavil for depression for 20 years. I did have some problem with not remembering that I had told someone something already. This has gotten better as I made a conscious effort to remember things. I still have some problems with memory in forgetting where I put things. The best thing that happened is I have not had a headache in 20 years. I used to have bad headaches 2-3 times a week so this has been well worth putting up with side-effects."
