Agree with Georgie here. It is important. Not just for health reasons, but for the head stuff too.
A lot is in the perception/attitude to it. If you approach it with "OMG, I get to eat...OMG..food...I'm never going to control this", then you'll probably find it tough. AAM is no big deal, try not make it one
Remember, you are eating already. You have food. You may even have bars which means you are chewing on something.
If you're worried about preparation time, yes, stick to something like cottage cheese. Really worried about eating it and wanting more? Then stick the cottage cheese in your smoothie (tastes nice) and treat like an SS day. You could always chomp the bit of cucumber on the way up to bed
Just until you get over the fear.
Do be prepared though. Get it ready beforehand. You might think that you haven't got time etc, but you will have to do this at some point. You just get a tiny little glimmer into the future.
This is your chance to practice facing the food, yet still be in ketosis so you don't have the hunger to deal with at the same time. We all need as much practice at that bit as possible before goal arrives.
