WW,
I am sorry to hear of your current Rx worries.
First have you talked to your prescribing doctor about this? What does he/she have to say?
Are you at the maximum dose then? If not, why not try another small increase...this could be all it takes to get you back to where you want to be.
I would definitely talk to my doctor about concerns though. He/she knows the closest, but different med to your current one that may be the most likely to help you.;)
Try not to project fears into the future. Take it one day and step at a time...you'll get this figured out and be fine.:)
Keep us posted.
S.C.
