Occasionally... as in very occasionally. They're just tasty.
The peanuts, just sort of happen. "Oh look... trail mix" sort of situations. I just don't bother picking the peanuts out- lol.
Peanut butter... I buy it sometimes. I go for the organic, and it's dirt cheap. I generally don't buy nut butter of any kind at all now, since I can't seem to control myself around it. I think I bought a jar last month, enjoyed it for 2 days, and was fine with it. Probably won't eat it again for another 3-4 months.
