I want to lose a few pounds!

I have eliminated all Splenda/Sucralose, due to a sensitivity reaction. I use the "blue" packets. My labs show I am a bit low on fluids, but since almost all my protein is in shake form, with lots of liquid, the Dr is OK with it. I even take all my pills with protein drinks. They upped my protein for surgery recovery, from total body plastics 2 months ago. Coffee is dehydrating. I eliminated all caffeine post D.S. surgery, Dr suggested. Occasionally have tea, but need real sugar for it.
