Citalopram
"First I started on 40mg and I guess my body got used to it.  I had to go up to 60mg and everything started getting better.  Then, my Dr. told me he had to take me back down to 40mg because a warning was released that anything over 40mg could cause a malfunction with the electrical signals in the heart.  I am back on 40mg and things are progressively getting back to where they were to start with.  I think I need to change medicines."
