Not even sips but it's natural from the beginning. Meaning that physically in the beginning, you'll eat so little that any additional water will make you feel uncomfortable anyway. Before you know it, it becomes habit. It still makes me so uncomfortable that even now I wait over an hour after I eat before drinking anything. I understand your concerns about vitamins too. If you hate swallowing pills, many of us have been using patches successfully. You'll have to see what works best for you. In the end, the weightloss will be worth with it and you will see how very little you eat, and will want to keep your body healthy by taking supplements. For months, I ate less than 800 calories. Even years later, many of us still do not eat enough to be well nourished. I totally get the fast food with our significant others as a bond but it is totally doable. My mister doesn't care what I order but I think he feels more comfortable as long as I order something. So let's say Taco bell ... I order a side of black beans with onions (50 cal). I don't think it is what I eat but that I have a meal with him regardless what it is. IF he ever insisted on me eating what I used to eat, then there is something really wrong with the relationship in the first place.
