29yo F, 5 8, 220- Sustained a concussion on Sept 24, 2013. I was started on Nortriptyline 50 mg for continous headaches on Dec 19, 2013 by a neuro. The Rx is slated for 30 days. Is there an alternative to this drug? It makes me very sleepy and even though I take it before bed, I still feel the side effects of it throughout the day. My history with medication is best summed up as a little goes a very long way. For example, half a benadryl is strong enough to put me to sleep in the middle of the day. Thanks!
