Hi Eagle Heart and thanks for the welcome back.

You are an intuitive eater. Butter is a natural product whereas margarine, transfats or not is not so your body does not know what to do with it. It does not process it well and that's, in my humble opinion, why you feel haywired--great new word by the way.
Butter is not a problem in the amounts you mentioned. It's a great source of tasty fat which digests easily for most. Margarines however are pretty much junk food.
Nice to be back.
