I get mine from Stater Brother's grocery store. Store label so no brand. I by the diet type as I can't use the one with sugar. $1.00 for a two liter bottle. Odd that it's cheaper than most bottled water. Side effects from drinking two liters in one day are the same as a full dose of quinine. Slight nausea and a bit of dizziness. Also throws gross coordination off a bit but fine motor skills remain intact. Side effects vanish in 48 hours completely. Doesn't seem to effect driving skills.
