Psyching Myself Up

It's starting. The dreaded Holiday Parties.
The first one is this weekend. It's a sit-down dinner at a Mediterranean restaurant. We ordered our meals ahead of time. I picked the vegetarian option.
1) I will not eat all day
2) I will allow myself 1 glass of wine
3) I will allow myself 1/2 piece of baklava
4) I will eat my entree slowly & stop before I am full

I feel panicked, slightly breathless just thinking about it. I'm not good at controlling my eating habits once I get started. It's a lesson I need to learn, though. This is a good opportunity to do that.

Chew slowly. Set down fork after every bite. Talk a lot. You can always take it home.

omg

So much stress over one dinner... I'm half inclined to bail, but I've already paid. I feel like I already made a good choice by not getting the lamb. So... I'm already ahead of the game?
It makes me extra super nervous to go out to dinner the day before a weigh-in.
I'm hoping for 185 on Monday, but I haven't been able to work out as much because of homework & I have a show tonight.
Think positive, weight-losing thoughts for me.
