Ive been on it a week, at 6'2", started at 226, now down to 222, and took a day off for a buddy's birthday and had a few beers and am at 222, the next day after, started back up on it again. It does make me a little drowsy, but much less so than the normal CKD, also I get no cravings at all, and my roommate eats Tater Tots and Pizza like 3 times a day, and I haven't come off it yet, cept to have a few beers on a Birthday. Cravings are not an issue, its just hard to get all hte peanut butter down, so in the morning I have 5tbsp of ANFB, and a scoop of whey, and then only 1 tbsp for the next meal with a can of tuna. Then the other 4 meals are pretty much on the money.
No issues with constipation due to high fiber content of hte ANFB, and at $1.86 a jar of ANFB, this is very cost effective
