Drinking during camp

A lot of fighters in mma and boxing have expressed their feeling about drinking during camp and even sex during camp . Some avoid it like the plague however there are those like Ryan Garcia and Tyson fury that do it here and there but don't get slouched . I have drank and sparred in someone else's camp and have done fine I just wanted to get your opinion.

Ps. This is also kind for me I am in my first fight camp not a full sanctioned bout but an exhibition.
