Beer with coke....gotta try that one Fitzy......
Hard up years ago night skiing....all we had was Dr. Pepper, Kahlua and Amaretto....mixed those in the bota...called it Dr. Kaletto....served the purpose
Used to buy that crap fad cola JOLT and mix it with whatever...typically rum......super sweet, super caffinated....guess its wwhat young people like about the red bull / energy drink mixed drinks....lol
*pukes a lil thinking about it now*
Popular soft drink combo here is Black Gold....half coke, half Dr. Pepper...we like that one....
Also try tobasco sauce in beer....though do not overdo that. Trust me.
I also enjoyed caffiene, but stuck to normal concentrations for the most part, and never dared try the new energy ones. Now I regulate even my coffee, with 50/50 being the most potent that I would try, except for may the occasional (3/year) or accidental(stupid waitstaff) full caff.
