ibromyalgia
"I took Lyrica for 10 years until the copay went to $100. So I began Gabapentin at 100 mg twice daily. It helped with the pain, but not enough. My Dr. increased the dose to 200 mgs twice daily, and I began having the following side effects after only 2 days: cold symptoms, bloated feeling, constipation, cough with mucus, excess gas in the stomach, excessive eye tearing, feeling dizzy and  lightheaded, indigestion, passing gas (a lot, plus, stomach pain from it), runny nose, tender glands in the neck, headache, bad taste (like eggs). I'm back to 100 mgs and the side effects are going away, but pain has increased again."
