I am so lucky, my hubby doesn't like the idea (or the expense) but now it's paid for, he's being helpful, has bought lots of weightwatchers and slimfast stuff, today cooked some cod in foil for me (I don't want to tell him the smell is making me feel ill at the moment!!!).
Regarding the tiredness, I get that badly whenever I go back to low-carb, I have found that the best help was vitamin B12. I bought some in spray form at H&B the other day, you spray it 2-3 times a day under your tongue, and it seems to be helping me out of my diet lethargy, so may be worth a try?
