I just made homemade buttermilk ranch dressing and ate a huge amount along with copious amounts of veggies.  Now I feel like jabba the hutt.
Just so I understand, are you saying that you feel like a glutton after eating so much?

While it's okay to satisfy cravings once in a while, you shouldn't go overboard like this. As you see, you only feel like garbage after having such a high in the short term, so you need to control yourself so you can enjoy things without being guilty.

I understand that it can be hard to control ourselves in the moment.  If this is a problem, perhaps you could make smaller portions, or immediately seal and refrigerate most of what you make, so that you are not so tempted.
