How do you guys do it?

I do IF most if the time and have done a few u 24 hour fasts (just extended my IF window when busy etc) but I've been wanting to try a 2-3 day fast to try to help with weight loss and something always comes up and I end up eating. If I have to go out and people are eating, it's almost impossible for me to say no. Do you guys just not leave the hiuse when fasting?
