Hi, I had my surgery on 1/18/10 the 21 days were easier than I thought. I took 2 week off work which helped tremendously. I was not really hungry but had to make sure that I stayed hydrated. As long as I drank enough liquids, water especially water, I was not weak. I drank tea, juice and broth. Towards the last week I started really wanting to eat mostly because everything was getting old, tired of soups, yogurt or anything liquid and was ready to get the next phase started. Once you make the decision to go for it everything else will be easy because you will have made one of the best decisions for your life. That in itself gives you the strength to get through the liquid phase. Hope this helps. Good luck!
