I'm afraid anesthesia will make me say/do inappropriate things. how can i avoid this?

Talk to your doctor: Many patients feel that they will talk and say very inappropriate things once the medications loosen their inhibitions. Talk to your doctor. Write a note that you do not mean anything you say while under sedation. Everyone working in the hospital will act professionally. The most important thing on your doctors mind is to help you. Talk to him/her and share your concerns.

Probably Nothing!: Most sedatives create a condition called antegrade amnesia in which a patient may have no memory of events that occur after the drug's administration. It is possible that what is said during that time will reflect some disinhibition. However, health care providers realize & discount the effects of such slips! moreover, hippa privacy rules legally Prohibit disclosure of such information regardless.

Don't worry.: Under general anesthesia you will not say anything. Essentially in this type of anesthesia you are so far asleep that we take over your breathing for you. Before you go to sleep you will receive a sedative agent which will make you more relaxed. Again it won't make you say anything inappropriate.
