It seems to be a little worse with whiskey and wine. Beer seems to be slightly less severe, but it's a subtle difference. All types have the effect to some extent.
It's been about a year. It came on gradually over the course of a few months and I started cutting back further and further until now I can't drink a single drop if I want to feel okay the next day.
It does happen with vodka and gin. Hard liquor in general seems to cause the effect faster than beer. Sometimes I'm able to drink a single beer and feel mostly ok, although it still gives me a faint headache.
I know it's not a regular hangover because I'm drinking such small amounts I'm barely even feeling a buzz, and I've tried drinking absurd quantities of water with the alcohol--like 8 glasses to 1 glass of beer--just to eliminate the dehydration possibility, but no effect.
I usually feel a vague discomfort in my head the moment the alcohol starts to "kick in." I still feel the "buzz," but it's accompanied by a feeling of heaviness and soreness. Even if I have my drink early in the evening, like 6:00 pm, it will remain until I go to sleep hours later, then it seems to transform into the traditional hangover--headache, sore neck and head muscles, foggy thoughts--while I sleep.
