Drinking, I'll literally daydream about drinking things during the day. Like if it's really hot out I'll imagine how refreshing a glass of ice cold water would be right at that moment. Or pepsi, or fruit drinks, or smoothies.
I can go for like 3 days being comfortable with no food. However if I feel a little parched, I can only go a few hours before I start to cry and get very moody. I need my drinks
but if i had to choose one i'd say drinking. sometimes i'll skip a meal and just have a drink. i find it easier being hungry than thirsty, so i prefer drinking
