This rings true to my experience. I found recently that I was having really bad 2 day "hangovers": I was fine in the morning, but weird stomach ache in the afternoon and feeling like complete shit from there into the evening. I thought it was just "I'm getting old and drinking a lot, this is normal", but it sounds like withdrawal symptoms are more accurate.
