Hello and welcome to Healthcare Magic. Thanks for your query.
There could be two possibilities for your violent behaviour and passing out after consuming a moderate quantity of alcohol - one is that your drink could have been spiked with some other psycho-active drug, or you could have had an idiosyncratic reaction to alcohol (which happens in a very small percentage of people).
However, now you have developed symptoms of headache, shakiness and dizziness
. Like you mentioned, these are unlikely to be alcohol-related, since your quantity of alcohol that you consumed is unlikely to due be causing any significant withdrawal effects this late. I would advise you to have a proper medical evaluation by a doctor to find out what is going on, so that appropriate treatment can be initiated.
Wish you all the best.
Dr. Jonas Sundarakumar
