Hi Martha and welcome to the family.
I have never taken Savella, so I really can't help you w/ that. We have some members who do/did take it, hopefully they will be along soon to give you their take on the med. Some ppl like it, others, not so much. We are an interesting lot, some meds work for some ppl - and not for others.
I was given Lyrica 2x, didn't help either time. Caused more problems.
When you get a chance, take a look at 'Fibro 101' at the top of the 1st page. It has tons of good info to help and enlighten you. I have read it and REread it. Especially, with the Fog, everything old is new again. lol
Hope to hear more from you. Have a wonderful day.
God bless. Alice.
