I am taking Lyrica for fibromyalgia and back pain. I recently discovered it can cause weight gain. Can anyone else comment on this? I need to know how to lose weight now. I've gained 10 lbs that I don't want and isn't good for me. The dose of Lyrica I'm on is 75mg three times a day. I took Gabapentin 9 years ago before my back surgery (L4/L5 fusion). My doctor tells me that Lyrica (Pregabalin) is stronger than Gabapentin. I'm not sure about that. I'm also unsure about what the optimum dosage for me should be (questions to ask dr.). I take enough meds as it is and don't want continual dose increases or new meds. I also have CFS. Ah, there is another question: what is CFS/ME? Any comments on any of this would be most welcome. Thanks in advance.
