Dinners with the TO crew often end up being 1.5-2 bottles per person. Recently at least one person has asked to keep it to one bottle per person, but it hasn't happened.
I'm 62 and not a big guy (5' 7" and 140 lb). I can't do 1.5 or 2 bottles without being totally incapacitated the next day. So now I take much smaller pours, skip some wines altogether, and drink lots of water. Much better.
