That's fabulous on the 4 month milestone. I never smoked, but my sister did, and my former FIL did and some friends have. It is no picnic to quit. Admire your continued fortitude.
I just wanted to say that you might want to find a new farmer to lease the tillable ground at your FILs. This guy doesn’t seem like he wants to deal nicely with Maureen and her sister. May be best to avoid trouble in the future or at least when the contract runs out.
