Contains alcohol - Why can't I stand alcohol anymore?

[_Nemesi_]

Sorry if this the wrong section to post this but I was wondering why I can't stand alcohol anymore. In the past nothing was enough to get me drunk, I could stand any amount of alcohol; now, I can't stand alcohol at all (like earlier I drank a glass of beer, which is not even half a bottle and now I feel like I got hangovers). Anyone knows what's happening to me?

Are you taking any medication?

No I'm not taking any medication.

If it worries you, you could go to a Dr. Does it worry you? well, I guess it must as you posted here, but not drinking is better for you :)

No it's not that it worries me, I would just like to know what is causing it. And then yes it's annoying too not being able to drink not even a glass lol *yes I know it's better but oh well xD*
