I didn't, but anxiety can cause this too.
Do you think that the side effects for Paxil have changed since you first started taking it, or is this the first time you've read the insert from the pharmacy in many years? I wouldn't think that it would change that much. In any case, I would hope that you are working with your doctor to properly get off the drug, and if you will still be experiencing anxiety, he/she will be very helpful to prescribe something else for you, if that's what is called for. Also, the doctor's advice will be helpful for your premature ejaculation situation which may be another symptom of Paxil withdrawal.
I have just gotten off Paxil 20 mg after 20 years. I will have to say I had terrible side effects. You didn't say much about getting off Paxil. Did you have as hard a time as I did. I am off 2 ½ months and have terrible sweating and heart palpitations until this day. Did you have that and did it ever pass? Don't know about the ejac's part as I am female. But, I still to not have desire for sex.
