First of all, if you do have fibro, sounds like you do, prescription drugs will make things worse, the foods you are eating will makes things worse.
Doctors are of no help, you need to get referred to a specialist that deals with Multiple chemical sensitivity if you are reacting to drugs, like I do. Wheat, exacerbates my pains, dairy exacerbates my fatigue, salicylates exacerbates my asthma and allergies. Fibromyalgia, chronic fatigue syndrome and multiple chemical sensitivity are connected somehow. I was labelled with Fibro, and eliminating all foods except fish, grass fed meats and poultry and white peeled potatoes, no fruits and vegetables as they contain salicylates, natural chemical plants have. Eating healthy made things worse, now I need to concentrate on other chemicals, carpets, laminated flooring, polyester, cordless phones, long times in front of PC, they emit VOCs when monitors heat up. Going to public places where people wear perfumes, use fabric softeners all give me headaches, dizzy, irritability plus many others. I recommend removing all foods, including fruits and veggies, start with meats or fish, add potatoes 3 days later, add another one ingredient food 3 days after that, NO PROCESSED FOODS, they contain, sugar, wheat and MSG. Cook from scratch only. If you can not get relief from removing wheat, or processed foods, eliminate dairy and sugars. I can eat white table sugar only, and not the GMO ones either, white peeled potatoes, skin contains most of the salicylates, grass fed beef, pork and chicken that aren't fed high diet of grains or sugar water. Organic didn't help, GMOs made things worse as they contain 7x the amount of salicylates. Corn is bad for me plus all food derived from corn(citric acid, maltodextrin etc...). DO NOT EAT MSG OR ASPARTAME....
I am working on getting to 1 of the only 2 Environmental clinics here in Canada, they deal with Fibro the best, so I've read. 13 month waiting period. Prescription drugs contain fillers and binders plus whatever chemical that could be exacerbating your symptoms.
Good luck, it isn't easy, but losing 75% of your symptoms is amazing, I can walk my dog daily now, I can breathe easier, I can concentrate better, my memory, although not great, got better. The fatigue is present still, but that may be from the chemicals in our environment.
