I have never felt any kind of euphoria with alcohol; experimenting, I've reached large enough amounts to severely affect my balance, coordination and concentration, but was otherwise hardly affected at all (as confirmed by a teetotaler friend who was with me in some of those times).

Some people, when I tell them that, respond with "well, what did you expect? that's drinking" and some with "that can't be, perhaps your vodka was watered down". Your comment reminded me of that.

Having experienced both versions (euphoric and non euphoric), do you have any insight about the difference, how much of it is physiological vs. psychological?
