Welcome to the site.
Well you see you did wrong to switch from Cymbalta
which also belongs to the same class of anti depressants (SNRI's) to which Cymbalta belongs to and savella too causes the same set of side effects as cymablta does although in less intensity.
So this explains why after 2 weeks of switching over to savella you are still suffering from the side effects, the reason being savella is not helping your cause since it also leads to the same side effects.
So I reckon that you ask your doctor to bring you off savella and shift you to a relatively safer anti depressant drug like wellbutrin
xl ( generic name -- Buproprion extended release) at dose of 150 mg / day to be taken as a single morning dose.
I hope this helps.
