We had guests (who nursed 1 glass of wine between them) and my girl had 2 glasses. I guess you will get about 4-5 glasses out of a bottle? When I woke up this Morning, there as 2 empty bottles and a 3rd that had about 1/3 taken from it............ I think I drank a lot! I felt fine when I got up, shower, walking, talking.... did not feel at ALL imparied. . . . Normally, I still feel either a little tipsie or just know that i'm not right... but today I was fine! STRANGE I thought...... but oh well, being a Friday I thought i'd take the bike in. I struggled to ride the 2kms to work! Very very very scary!! amazing how much different riding is when "your just a little off".
