I've had a few where days 4-6 were the hardest! And cheese is something I ALWAYS want. During one MC, I dreamed a LONG dream about eating big slices! I woke up so mad at myself until I realized I hadn't really eaten anything...
Hang in there, and you'll feel better. Maybe you could change it up by using limes instead of lemons for a day or two. I actually prefer limes.
Also, if you're still hungry, drink more, or if you're skimping on syrup, add more. Somer uses a spoonful of blackstrap molasses, and gets a big boost from it. Maybe you could try that. You have come so far; don't give up now!
