Another weigh in.

So I usually do my weigh ins on Sundays, I don't really know why but I like that day. This weekend I did it on Friday morning because I knew this weekend wouldn't be the best of eating weekends. So I got on the scale and it said 188.8!!! I was so excited I haven't been under 190 since around Febuary. At the same time I'm a little worried about ruining it. Hubby wanted to do a date night yesterday and then tonight I am going to sushi with mom so I know I'll be retaining a lot of water because of the high sodium so my weight would be off if I would of have weighed myself Sunday. I'm not planning to go crazy but I dont want to be disappointed tomorrow morning. Also on Monday we are going to a bbq at the father in laws I may bring some fish for him to grill but not sure yet. Anyway I didn't do too bad last night. We went and had Mexican food we ordered a quesidilla to share which I probably could of have done without and I had fish tacos but i only had one because I didn't like it at all and a few chips and salsa. We also had frozen yogurt that was delicious by the way! This morning I had my breakfast shake because we were having a  meeting at work, they usually always bring doughnuts so I figured that if I have my shake in the morning I will not have one. Well that backfired, through the course of the day I have already had 2. I don't understand why I don't have any self control. but I'm not going to dwell everyone has an off day and I will work harder in my workout. So tonight my plan is to have sashimi which I don't see being too bad and maybe sharing a roll with my mom at sushi I was going to have some wine but decided I don't need the empty calories after my day and last night. What do you do to recover from falling off the healthy eating wagon?
