Thanks darkeyes for your reply! My doc mentioned Effexor but he said it's much more expensive. So I chose Nortriptyline...I also love dogs..too bad my mom doesn't let me have one in the house now...my previous dog died a few months ago, and I was desvastated...my mom doesn't want me to go through the pain of loosing a pet again...I really miss my dog...I used to think I couldn't live without her. I am doing ok now.
