I have 4 stages.
Stage 1 is sober.
Stage 2 is tipsy and that happens after just one beer/drink/glass of wine. It's nice for everyone, myself included.
Stage 3 is starting to lose control a bit. Usually happy and manageable, but I'll get a hangover from it. Others have said I'm fun. I can get emotional easily.
Stage 4 is shitfaced. I wish there was another stage in between this and 3, but unfortunately if I'm not careful in stage 3, stage 4 will suddenly crash in. I most often get memory loss (partial or continuous for hours) and I'm realllly bad the day after. People say I'm fun but annoying here since I don't listen to reason and tend to blabber on and on. I get intensely emotional easily. I really just know what others have told me about this. I try my best to avoid this these days; this year it's only happened once and I'd like to put that number down to zero next year.
Stage 2 and 3 are fun though :) and yeah, stage 2 happens easily and is fine, stage 3 I get to by conscious choice.
