Tried it a couple a weeks ago in a roomful of responsible supervising adults.
A couple of drinks made my muscles feel very relaxed. Like someone had "loosened my strings." But that's it.
I couldn't hold my glass as securely, because my muscles were so relaxed. I kept dropping the silverware, because I couldn't get a good grip. I was, however, able to walk in a straight line.
I didn't feel any more talkative, nor were my inhibitions reduced, thank goodness!
I found the experience to be very unpleasant, because I hate not being able to control my muscles. I wonder what would've happened if I had a few more drinks.
Besides, alcohol tastes bad, even when mixed with other beverages. To me, it is NOT worth drinking a yucky-tasting liquid in order to experience undesirable symptoms.
