I drink about 2 nights a week and have been doing so for about 3 years now.  I have felt very sick before like to the point of almost throwing up but i always either sleep it off or take motion sickness pills because throwing up is like my biggest fear.  (i havent thrown up in 7 years)  i just feel like i need to get over this fear though especially because my 21st birthday is coming up!  any advice?
