Working while on the MC

I'm just curious about going to work while on the Master Cleanse. I work an elementary school, so you can imagine that being around lots of little kids every day is demanding, and I have to give a lot- it's hard to take time to check in with myself while being a work. I don't know, I guess I'm just scared of feeling spacy or sick while being at work- but I suppose that is just a risk you have to take while on the MC? How do people handle detox symptoms/hunger while working? Any advice would be Great! Thanks.
