Hi Jennifer,
I'm sorry about all these symptoms you're having, it sounds awful! I am on Savella 100mg twice daily for about 3 years, my doctor said that sometimes with fibromyalgia, a higher dose of Savella is needed so I'm on the highest dose that is safe. Fortunately for me, I have not experienced any negatives to Savella, it felt like it just ended a lot of my whole body aches and I love it. I feel so horrible if I don't take it.
Of course, like any med, Savella is not for everyone. If I were you though, I would wait at least a week at your full dose (after the initial weaning) and then reevaluate how you feel.
I hope things do work out for you!
