I have had excellent results with Elavil. I couldn't tolerate Neurontin because of significant mood changes. I also found with the Neurontin that I would have a "honeymoon period" with great symptom relief for a few day after each dose increase, and then my symptoms would gradually return. I started on Elavil in August at 20 mg in the PM. After a few days I added 10 mg in the AM. I initially split the 10mg taking 5mg in the AM and 5 mg mid-day which seemed to decrease the sedative effects that I was experiencing. By September I settled into a dose of 10mg AM, 20 mg pm with excellent symptom relief and significantly improved sleep. The only long-lasting side effect that I've experienced is a bit of tendency towards constipation. About 1 month ago I increased my PM dose to 30 mg because of the return of some sleep difficulties and have had an excellent response. The best news, which I haven't shared with anyone yet, knowing that, in all likelihood, it probably won't last, is that my body-wide symptoms are at the lowest level ever. I'll just have to enjoy it as long as it lasts
