This forum is a great way to find support! Sounds like this could be a good opportunity to find your strength and something to look back on as an example of the things you can accomplish when you put your mind to it!
I would think that eliminating the MS would make it harder to function as I think the only thing that saves me is the sugar content of it, think I'd really be dragging without that, but every body is different. On my first day when I could hardly get anything down and could keep almost none of it down I decided to stick with it for 10 days no matter what. To add nothing and to do as much of what I was supposed to as possible. I don't know that Peter would agree with that, but that seemed reasonable to me. I was determined to do a little more each day and I was happily surprised to find that I quickly worked up to doing everything (except the SWF) Personally I think as long as you're not adding anything it's ok to cut yourself a little slack and give it a few days, but that's just my opinion because that's how I deal with myself and it works for me.
Best of luck, I'll be here for you if you'll be there for me!
I have to add that I'm at work and all the customers smell like food, I'm choosing to dance for the ones that smell like the things I'm hungry for! Lol
