Oh, here is a good one, BUT you'll have to be consistent to avoid getting caught with this white lie....tell people who do ask that you're currently taking medication for some "allergy", "headache" or other believable problem w/o obvious symptoms, lol!

Most people will back off after you tell them that. If they don't, and they have the nerve to ask you what medication you're on, then just tell, them, oh, I don't remember, it has a really long name, but all I know for sure is that my Dr. told me that taking it with alcohol is a no no. lol. Then change the subject abruptly or leave if they become nosy. Make an excuse to make a call, talk to someone else, etc....lol.
