depending upon your reaction to alcohol this may not be the best thing for you.
some people get violent when drunk, and that's all they need is some freaked out passenger on the plane screaming slurred words.
Plus if you get air sick then you'll be doing plenty of throwing up.
Talk to a doctor, they'll prescribe something that'll calm you down.
I suffer from panic attacks, and any type of stimulant can trigger them.
Anyway my point is I about freaked out when I went to the dentist and he injected the novacaine *which in this case had some adrenaline mixed in*, they rescheduled, shot me up with some adovan and dude I sat there so fucking calm like when they shot me up with the novacaine. No reaction whatsoever.
