Just got a quick problem... when i first turned 21 i could go out and have a few drinks without suffering at all the next day...However i did this several times a week. For the past year to year and a half if i have 5 or more beers in one night i am near death the next day. It honestly will take me the entire next day to get back to normal... and sometimes even the day after. Is this something i should be concerned about.. i have had blood work done the last few years and my liver function is perfect. Could it also be because i am getting alittle older... im just looking for some explanations for why im such a stinking light weight when it comes to having any alchohol.
