I think, for me at least, I have to take it one meal at a time. I am not thinking long-term now. I stock up with low-carb foods that I enjoy. I am thinking to the next meal. What can I have that is healthy and low-carb? Then I plan my next meal. It is hard getting back on track, and even more frustrating when you can see that going off the low-carb has landed you back where you started. Live and learn. You did it before, so did I, and we both can do it again. It probably won't be the last time either of us fall off the wagon. The important thing is never to stop climbing back on. We both know we felt and looked better when we stay the course. For me, those pics were a real wake-up.
I hope this doesn't sound shallow or crass or that I am making light of the situation, but I often think of people in impoverished countries when I feel "deprived" of sweets and other high-carb goodies. Those people have never, and will probably never even taste such things. They'd be happy for anything to eat, low-carb, no-carb, it wouldn't matter. So when I am sick of eggs, I think, "At least I have these eggs! I should be grateful. I have unlimited access to fresh water, when so many do not. I can take a short walk to town and get fresh veggies whenever I want. I don't have to work a whole day at hard labor to get the makings for a salad. I have plenty of tea. I don't need sugar in it to make it taste good. I have choices, plenty of choices to eat that will make and keep me healthy."
Despite all the technology advances and medical advances, we each only get one body. We also have more information and knowledge than diabetics did in the past. We are very fortunate in that respect. It must have been horrible many years ago to really have very little info to work with. At least we *know* what to do. That is a big head start. Keep reminding yourself how well you felt before you went off-track. Tell yourself you *deserve* to feel that way again!
