Essentially, you are on two drugs at once now, and could be suffering withdrawal from the Zoloft, side effects from the Cymbalta
, or a combination
both. If you had tapered off the Zoloft
as slowly as you needed to and
not started the new drug until having successfully completed that, you'd know if this was a withdrawal symptom and perhaps you needed to slow down the taper off of Zoloft. By being on both drugs, you have no idea what's causing what, and neither does anyone else.
