After taking just one dose last night, today I had very little pain but I feel very tired. Last week I could hardly walk from all the muscle and back pain. My legs just wouldn't work anymore. I was diagnosed with Fybromialgia 20 years ago but we had no Lyrica back then. Since then, I've been on increasing amounts of pain medication and diagnosed with degenerative disc in my lower back. I also feel like I am in another world from this medication. I don't like this feeling at all. Will these symptoms go away with time? Anyone experience this?
