is this a sign that I'm getting older?

I decided to have a drink tonight; so I stopped at the liquor store and bought 2 airplane bottles of orange vodka, and a bottle of raspberry & black currant sparkling water.

I haven't even finished my first drink, and I can already feel the buzz. One measly airplane bottle! Does anyone have any idea how much I used to drink in college?! This is pathetic! I'm pretty disgusted with myself right now. *g*
