actually considering there are breen's private reserve cans in the junkyard in episode two and IN KLEINERS LAB RIGHT NEXT TO HIM the drinks and the forget water are probably seperate(???) otherwise why are resistance members just actively drinking water they know is chemically altered to impair them. but then the question is what is the drink and why does it look like cans of plain ass water?? it might be completely unrelated water. it seems like they got cherry and lemon too if we assume blue is Water and the other two cans are just variations. maybe there's diet... water? or some other drink entirely like one of the sodas we also see littered around the city - like a sprite or cola or something. i also would love to believe red is actually watermelon due to all the goddamn watermelon props
assuming alyx is more or less faithful to the events prior to hl2 (timeline fuckery notwithstanding) there are also those water flavored desiccated sustenance bar things in food rations that is maybe related? it is of course also possible the citizen is talking out his ass and just assumes random unprovable forms of control when in reality the combine are just exercising ""Normal"" forms of control. i also do wonder if the trash we see that has like regular milk cartons and chinese takeout and Combine Branded Hamburgers is indicative of some low level fast food industry that continues on. there might not be meat livestock anymore but there are definitely tons of produce so there's gotta be dome sort of edible normal ass food going on
edit: i have considered that there might be a "safe" version of DR> BREEN for breen/mossman/metrocops and the like and an unsafe version that you can get as a citizen. it would be relatively easy for rebels to get a hold of the safe version which probably tastes less awful. honestly there's not a ton of competition for beverages anyway
