I've had the same problem with paxill for the longest time. I just stopped taking it and have noticed a little bit of a difference but, I think it will take a while to get back to normal. Don't worry though it's not permanent.
Yes you will get back to normal when you finish taking it, also this side effect might lessen.
Been there, it is awful
One month is still not enough to say if this side effect will persist but yeah it wont be a problem once off the drug but it might take like up to a month until you're back to normal.
