Yes, I had ulcers in my mouth. too. I almost asked the prescriber about them; but, soon after that, I totally quit the drugs and they were mostly gone. However, when stressed, one or two may flair up for a while and then go away. Of course, like you, that’s not the only issues I dealt with while on the drugs and then there was the withdrawal. sadly, even after the withdrawal, there are still issues in which to contend. However, since none of the drug-makers or the psychiatrists, etc. want to admit all this; it is very difficult to know how long any of this will last. But, since the brain is definitely involved, it may be lifelong. Thank you.
