Sorry to hear that you still have to deal with temptations around you. Darn those kids!
Here are some ideas for go-to snack foods. (One of my first posts here was looking for ideas to fill that nitch.)
• Make popcorn - as in the kind you cook in a pot on the stove yourself. It is a good comfort food, has that crunch and a touch of salt that we crave, is high in fiber, and is filling. And you can make enough to share with the family (or have for stale leftovers the next day).
• Switch your family over to some gluten free foods as well so that what they are having doesn't tempt you to hurt yourself. Pasta, pancakes, brownies, cookies. There is no reason to bring the gluten versions into your house ever again.
• Or hide your gluten-free snacks someplace where the family won't find them so that they haven't disappeared when you need them. Cookies can easily be hidden in the freezer.
• Make a trip to a grocery store that is known for carrying organic or health foods. They'll often have a lot more gluten-free options to choose from, and will be likely to have a big gluten-free label on the shelf or have a gluten-free section. A few of the gluten-free items I tried early on were pretty awful, but 90% of them weren't that much different than the gluten versions when it came to taste and texture.
• Drink more water
• Get tested for vitamin deficiencies. They are common in those with celiac and can cause cravings despite that the foods we turn to likely won't help at all. Getting any deficiencies fixed can also mean faster healing, better mood and energy levels, and help avoid additional symptoms caused by the deficiency.
• Look for the less obvious snacks that are already in your house. I can't tell you how many times I've opened up a can of olives because there was nothing else available in a pinch.
• Keep coming back to the forum for support. These people were/are a HUGE help to me.
• Get yourself some gluten-free beer?
• Have snacks on hand for yourself ALL of the time. Half of my accidental cross contaminations so far were from when I ran out for what I thought would only be 2-3 hours and it turned into 6-7, forcing me to find something to eat on the go. I still get hit frequently by low blood sugar simply because I don't eat when others are eating, and am only starting to realize that I can pretty much find gluten-free juice anywhere I go.
• Do research about how to decontaminate your kitchen and hidden sources of gluten. That is a great way to avoid accidental contaminations. My rule is to simply not buy any pre-made foods unless they actually say on the label "gluten free".
So here is the good news. Once you are completely gluten free, your stress reactions should drop considerably. Those I know in real life who are gluten free use words like "calmer", "more even", and I say "dulled". And you'll sleep better so you'll feel more rested.
However, damage to the intestines aside, you have GOT to stop the glutenings you know of. Gluten is an opiod peptide, which means it fits into the opiate receptors in our brains, gives us a feeling of a high when we eat it, and has withdrawal symptoms. Those alone should be enough to keep you from knowingly ingesting gluten. So you're noticing the stomach issues, but the irritability, the headaches, and the brain fog are all part of the reaction as well. And every instance takes days to recover completely, if not a full week. Just having an accidental minor contamination once a week could be enough to keep you in a perpetual state of miserable!
You already know you have to do better, just need to find the resolve. I'm certainly not going to beat you up because your body is already doing that.
But start paying attention to the little things that are improving once you manage to stay gluten free for a week and have gotten through most of the reactions and withdrawal. I can probably rattle off two dozen things that cleared up when I went gluten free, things I thought were just part of aging or never imagined were related to gluten. Someone should restart or resurrect one of those old threads of things that got better. It is a great motivator to realize that you've got the same improvements as well.
