I was wondering about PDU as well? I hope he's okay!! I hope this new medicine works for you. I'm on day 5 of Nortryptyline and I've noticed an increased in energy and happiness, but still have intrusive thoughts that I have to find throughout the day. I'm better when i'm at work that when i'm sitting idle doing nothing. My therapists believes in CBT and I find that it does help me see how irrational I can be. I hope this is the right med. I go for a med review next week.
