Hey, I have found you!
Come on lovely, we can do it! You seem to do the same as me, when you have things going on, healthy eating goes out of the window. I am a sucker for thinking "oh I am going out tonight, I may as well be naughty today!" and then not getting back onto the plan the next day.
Lets just put things into perspective, this is a healthy eating way of life, as long as you don't need to lose the weight quickly, you should still be able to enjoy life and eat what you want when you go out. I see you aren't folloing a specific plan, but incorporating with exercise. Why don't we try this, for everytime we fail/fall or eat out, the next day we go to the gym, or do whatever form of exercise you do - drink loads of water and get rid of the naughties from the day/night before.
When is your next naughty time? Mine is Friday, so today I vow to be good, tomorrow I vow to go swimming in the morning and gym in the evening and Friday I vow to be good all day long (and maybe do a kettlebell work out in the morning) and eat well all day and then have my blow out in the evening. Then Saturday I vow to go swimming!?
Obviously, you don't need to take my advice on board, I am much heavier than you and failing miserably, but I am trying. In fact I am going to copy what I have just suggested to you and I am going to stick to it.
