I have been trying to figure out why I get major anxiety and feel really wired within 15 minutes of taking nortriptyline.

I went to donate blood today and found out that my pulse was 122! My pulse is normally around 70-75, so this was way high for me. I monitored it all day, and when it started returning to normal, I felt more normal (not wired and anxious).

I'm thinking the racing heart was due to the nortriptyline, because thinking back, the anxiety issues started when i started taking it, and rapid heartbeat could be causing that.

I am going to skip it tonight and see how things go, but am guessing that I am not going to be able to take it anymore.

This is the 2nd tricyclic in a row that has caused problems. I hope they can find something else to give me to sleep.
