buzzballs

i bought a biggie buzzball and i can’t finish it all now and i dont have a fridge to put it in. could i drink some then store it unrefrigerated in a dark place for a few weeks? for how long? the bottle will stay in a container so nothing gets in but i cracked open the seal not fully but it leaked a bit, i just dont want it to go to waste (its the berry cherry one it has no dairy)
