Nortriptyline
"I just started on this drug 2 weeks now. My doctor prescribed it to me to help deal with my concussion headaches and to help me sleep. The pain-free aspect is quite lovely, however 2 weeks in, and I'm suuuuper groggy. It doesn't help me sleep, but I didn't have a problem with that - it was just the post-concussion headaches. My doctor's main goal seemed to just send me back to work. I'm glad I didn't have to drive into work today because I'm not sure I'd be up for morning rush hour traffic. She only prescribed one month's worth (10 mg pills) & I can't wait to be finished with it. I have noticed a large increase in "chubbiness" around my mid-section. I notice that some weight gain is one of the side effects as well."
