yes you can drink it but

you have drank worse things i am sure

it is best to make each time you want to drink that way the enzymne can't spell
won't have changed

I am doing it right now with Sugar cane juice I have to buy it everyday because I can't stand the way it taste

your stomache might just feel a little gross suggestin keep it super cold then drink other or sqeeze lemons then add it later

good luck
