I never measured or counted my spices/herbs or even my Molly McCheese, Butter Buds or butter spray. Well, actually I did for a time when I plateaued but it didn't make any difference and boy was it a lot of work.
I DID keep track of my Splenda after the first month or so. I was using a lot of the SF syrups in my shakes & oatmeals. I don't know if that affected my rate of loss or not but I just didn't feel that it was healthy to have too much Splenda. I switched over to flavored extracts instead. I didn't count them either.
The 3 condiment/day rule was one that I broke...probably most days but I tried to follow everything else as written.
p.s. I did notice that I did get into trouble with condiments when I was making a lot of the MF recipes. Too many recipes per day can really add up the carb count. As time went on I ate most MF meals as is. Just a thought.
