thank you for posting your query in healthcaremagic.com...
well according to your history, what you experienced is called
amnesia....generally following large amount of alcohol intake or
binge drinking, these kind of things are likely to happen...but you are saying that you only had a glass of wine which is unlikely....
anyways, can you tell me whether you are a regular drinker or not?...do you have any co-morbidities like
hypertension,
diabetes etc?...has sudden
loss of consciousness or mild forgetfulness has ever happened to you?
get back to me with these answers and i can tell you further regarding your problem...
as of now, you need not be afraid as it is n;likely to happen again following a small amount of alcohol intake....
however, quitting drinking is not a bad option, so i should rather not discourage you on your decision....
hope this was useful...
contact me for further queries...
regards
