I would def consider Diet changes if you suffer fibro...Do an ALCAT test and or YORK test and it can show you foods to avoid...also do a candida and hypoglycemia diet for at least 3 weeks...it will help and its not permanent just to fix your gut issues which can cause an array of symptoms.

Also you could try a neurotransmitters test which is done eithe rthrough blood plasma or better urine(Amino acid therapy)..Better than taking drugs....Also wellbutrin is good but it affects dopamime only and doesnt do anything to serotonin and heard it can cause anxiety but its good for add and concentration etc.
