in my experiences, drinking anything but your alcohol, will make it more likely for you to puke, i mean it's ok if you have to have it, but if you don't really need it, just drink the liqour, or drink as little of soda or whatever as possible... also, don't mix your alcohols, pick one thing and drink that exclusively... no drinking beer/wine liquor/beer liqour/wine... i mean some people can handle it but you obviously already have problems with handling your alcohol.. which i dont' blame you, i was only able to drink without getting sick a couple of years ago... and i had my first alcohol when i was 14 (first time getting drunk, i had stolen one of my grandpa's beers when i was like 9 and thought it was the most disgusting thing ever.... probably didn't help it was Busch)

and remember take it easy.. one single shot's worth may take awhile to kick in, but your body can only process a shot at a time, anything after that shot is just building up.. for your first time trying to hold it normally... take it slow, find your limits, then don't push them, use that as guidance from that point on... and don't do alot of jumping around or acting stupid once your drunk either as that will more than likely end up in the same end result

take care with your drinking!

unless you're absolutely sure it in the end doesn't make you sick do not drink and smoke... lots of people get sick from drinking and smoking... even i get 'sickly' if i drink enough to get drunk and smoke... it intesnifies the dizziness..
