At about a pound a week, yes, you might, I have a similar goal but I have to say I am really hoping I can actually get it I may more like only get 5-7lbs by then. I replied in your other post but your date was June not July.
Sure you can, but whether you SHOULD or not is another question. You mention elsewhere that your doctor has you on Ensure - that isn't usually because you need to lose weight. I'd go back and ask him/her this question and listen very carefully to the answer.
