It's been almost exactly a year since I've been legally able to drink. (Of course, I haven't yet, though I prollu should get an idea of what a standard drink would do to me, at some point. I'm guessing it will hit me really hard.)
It will. Thats from personal experience. My first drink was a Tom Collins, instant buzz!
Make sure you also have a full stomach, it will slow the alcohol absorption. Also be careful of meds compatability.
