Tell your surgeon about your experience, then ask to talk with your anesthesiologist so you can be reassured it won't happen again. Some people have trouble with certain anesthetic agents, I do so will be getting my previous Anesthetia reports to give to the anesthetist I'll have for WLS.
First time I had anesthesia was for a Hyst, I was scared but the anesthesiologist talked with me beforehand & then I felt better.
