FLAVOR: It tastes mostly like a kind of syrupy energy drink. Not terrible, not great. Vaguely citrus-y, very sweet. It does not taste like it's been laced with pot or a rope or anything.
EFFECTIVENESS: I'm about halfway through (it's only an 8-ouncer) and I think I'm perking up. I struggled to get up at like 3:30 this afternoon, so really anything helps, let's be honest. I did the dishes and have moved on to other household chores and am rocking some '90s Sarah McLachlan, so yeah, it's probably working.
OVERALL: Okay! It's nothing special except for what it's made out of and obviously they don't have fridges at Spencer's so I had to take it home and put it in the fridge so make of THAT what you will.
