Generally Lyrica causes weight gain. Lost 57 pounds in 14 months, are you doing anything differently?
Have you considered trying an anti-inflammatory diet to help with Fibromyalgia pain? I have fibro which is inflammation and inflammation begins in the digestive tract. After 8 years of aches and pains I tried it in May and by resetting my digestive tract...I'm doing well. Foods that are to be avoided: grains, cows dairy, prepackaged foods, cookies, etc. However there are lots of foods that are approved.
Been pain free since...unless I have ice cream and then I have pain for a few days.
Lyrica helping with blood sugar? Could it be your weight loss that has helped instead?
Hope all works out well for you,
