You could also snort pure caffeine.
if I had to say anything: starbucks refreshers are great if you don't like the taste of coffee. It's caffinated with coffee, yes, but it's masked by the savory flavors. Idk.
forget drinking caffinated stuff;just take it straight up, or if ground it up and douse it in OJ or something
I don't think it's a good idea to be drinking that much monster energy

Oh, also whatever you suggest it shouldn't be milk based.
