Jeanette,
I can sympathize, I had several challenges in the first few weeks and I can remember really stressing over them, but I was more worried about "appearances" than handling the food. I have this strange obsession with not telling anyone other than my husband and kids about the diet. Even my step-daughter who lives 10 minutes away and with whom I spend quite a bit of time, doesn't know about the plan. I think that in some ways worrying about people knowing I was on the plan somehow distracted me from worrying about the food too much!!
My best advice is beverages. Have a shake before you leave home so that you aren't too hungry. Bring a bar with you in case you get too hungry or get delayed, or keep a Ready-to-drink shake out in the car. Keep a beverage in your hand the whole time you're at these events. Circulate a lot and no one may realize that you aren't eating. If nothing else, say that your stomach feels just a little "off" and you're trying not to eat anything too heavy -- then move around some more. Sipping diet soda, or coffee or tea makes you appear to be partaking, but not "blowing" the plan. If push comes to shove, fix a plate and carry it around. If they have veggies and dip, that is perfect. Put some carrots and celery sticks on your plate along with some other odds and ends (but no favorites!!) and walk around munching on the celery -- then when no one is looking, pitch the plate.
Offer to help in the kitchen, or watch some of the other kids at the christening... any thing that keep you busy.
Once you start to have some successes at "ducking" food, your confidence will grow.
I had my grandson's birthday at my step-daughter's house about a week into the program. I was sure my cover was going to be blown, but no one noticed. I made the cake (and survived without tasting!!). When it came time to eat, I fixed plates for my kids and then grabbed myself a diet soda and moved into the living room. Yeah, my kids are old enough to fix their own plates, but it put me in the kitchen near the food, and I'm sure everyone assumed that I was fixing my own plate... No one noticed or questioned me. I got more confident after that. When the time for cake came, I said that I was watching my carbs and I had had enough "junk" already (hey, I've had plenty of junk in my life so I've had more than enough!). If pressed, I would have taken a piece and walked out to the living room and sat it down while I went to get a soda, then later, toss it!
My second big challenge worried me for over a week. We had a pharmaceutical rep bringing in lunch at work. We're a small office with 5 people, it is very hard to dodge things there. The "deal" really is that they bring you lunch so that they can "buy" and hour of your time to "talk-up" their products. I absolutely couldn't leave, couldn't figure out a way out of it. Finally, I fixed a plate and carried it to my desk and sat it down. I came back in and grabbed a diet soda and talked to the rep for a while, then talked to my co-workers then wandered up to my desk to "make a phone call". I stashed the plate in my desk drawer and wrapped it up later to take the "leftovers" home to my husband. (I could have just pitched it, but I knew he'd love it!).
As for your husband, that has to be the hardest one. I guess the best things I can think of is the chicken noodle soup and oatmeal. If you're eating with him, fix one of these and it will appear like regular food. I don't know your exact situation, but if you can at least say that you are dieting in some way, that has to help. If you can be "watching your carbs" or something, it at least explains a little bit why you aren't eating some things.
If push comes to shove and you are backed into a corner, you can always save this for an emergency... You can tell people (if really pushed) that you're having a medical test done on Monday and you need to be on clear liquids for two days. Many docs have you take clear liquids for two days before a routine screening colonoscopy.
My mind works overtime and I think out scenarios, but you'd be amazed at how little attention that people pay to what you are eating!
Good Luck with your challenges, I'm sure you'll do great!
