DinaMiller6450 20 Posted April 10, 2012 I started the liquid diet yesterday to try to loose at least 15 pounds. I do not need to do the liquid diet yet because I don't have a date yet. I am just trying to loose the minimum amount of weight my surgeon said I would need to loose before surgery. I woke up this morning with a headache and hungry. I had my morning shake and a bottle of Water. I took tylenol, but it is not helping with my headache. How long will this last? Share this post Link to post Share on other sites
