Hey Alecto,
I don't want to step over the line with my reply, so this is just my thoughts, take them on board, or not.
If I posted about doing something which could potentially kick me out of ketosis I hope that someone would step in and say something.
You worked hard to get into Ketosis and it would be a pain to have to go through all the hunger and such again to get back to the point you're at now.
If you are looking for a 'reward' why not treat yourself to a new top in a smaller size or something like that? Reward yourself for choosing to stick to your plan.
If it's not a reward you're looking for but an excuse to go back to old habits then recognise your thoughts for what they are, including the potential consequences and how you may feel tomorrow about the choices you make today.
If you do decide with full knowledge and understanding of what you're doing, then do it with a happy heart, enjoy yourself and don't feel bad about it tomorrow. You can always start again.
