I don't think there is anything wrong with knowing your limits. I cannot have junk in the house. No cookies, no crackers, no sweets. I can't even have graham crackers. Nothing that I can quickly grab. But I can have low-fat ice cream (I have never been one to eat out of the tub) in the house. I have that at night, measured out. Go figure!!
I think that learning our limits is an important part of our journey!
Congrats on being 1/2 way to goal!
