I found that when I was taking Klonopin for anxiety due to trauma event that has caused long term PTSD, it had a rebound effect each afternoon when it was wearing off. I was finally able to stop that medication after six years.
I was started on Neurontin in 1999 for Fibro and once I became intolerant of it moved to Lyrica.
I now take 50 in the morning and 50 at night if the pain is bad. I did take 100 x a day, but as I can gotten much older, I need less ( now age 76, diagnosed at age 43). I have never stopped exercising though, which really helps when you have this condition. I also have always used a very old muscle relaxer which works well if you must work. Skelaxin- and there is now a generic also. I use this two times a day 800 mg per.
