I've done sugar free before (but still eating grains like rice, quinoa, and home made bread without sugar added) and I do feel a lot better after only a few days. Cravings kind of subside, appetite decreases, and when I do get hungry its not that urgent need to stuff my face hungry, i.e. blood sugar isn't plummeting from sugar high...
But I have found that the one time I actually went all carb free, I was doing the south beach diet phase 1 and omg, craving were 100% gone gone gone!! Urge to binge was ZERO. I actually felt even better.
Ok so the problem, and here's where I want some opinions...It was almost impossible for me to exist outside in the world. Seriously, in my owe little bubble at home, no problem, awesome meals no issue, but one day out and about (say we go shopping for the day), and I'm stuck. (both sugar free and carb free) so many hidden ingredients, and not every place we go has eateries that offer foods that would work...
And the second problem is my family. Not my husband or kids, because he is very supportive and my kids are young and really don't care lol, but my extended family, we often have get togethers and they cook, and in the past I was a vegetarian (for several years) and they never respected it and often I just wouldn't eat at their house. But I took so much flack for that, that I don't feel like taking flack for "a new fad" (as they put it.)
Actually around thanksgiving last year I was sugar free and turned down a slice of pie and my dad rudely launched into a speach about how I was too thin, he was actually watching everything I ate or didnt eat. I of course told him it was not of his damn business. And by the way, my ticker is wrong. I'm now 176 lbs. So I'm sure dad is happy to see me fat again. Ugh!! I should note, I had a miscarriage in May and just couldnt bounce back from it. I tried but I got really depressed and stopped running, strted binging...but I think I'm finally ready to pick my self up from it. Especially since I dont fit into any of my clothes.

But I'm not happy. I need to be carb free, because I inevidably end up binging oin carbs, even whole wheat sugar free bread, or rice, nope I can not be trusted with carbs. Also I lose weight better without carbs.
Anyway sorry to vent
....any input would be helpful.
