When I started SSRI's, they initially had a positive outcome. After several months, I felt very tired all day, and even though my mood improved, I was kind of upset that I had no energy to do anything.

I was advised by my pdoc to take them before bed instead of in the morning to wear out the sleepy side effects, which did work at first.

Being bipolar 2, I did notice through the SSRI's and talk therapy, my thoughts began to slow down (I guess from being tired all the time) and I was able to handle my racing thoughts better.
