I don't know if this is caused by Budeprion or not but shortly after starting about a month ago I began having extreme difficulty swallowing, usually in the evening. I was taking 100mg and my Dr. bumped me up to 300XL last week. I was already having the swallowing problem, though. It seems to get better if I take a Alprazolam (generic for xanax). I hope this isn't a panic attack type problem. Has anyone had this type of problem for any reason? It is really scary. Thanks for any reply.
