cream soda doesn't make me sick... i can down like 6litres of it if i want... it's banana and sprite u gotta watch out for... my friend said u could get high on it if u stuff 2 bananas in ur mouth, chew and swallow FAST then down a litre of sprite... turns out what REALLY happens is the potassium mixes with some other chemical in the banana causing it to go acidic and expand... so it all came out my nose like 10 seconds after and it hurt my stomach and nose like crazy
