MLC,
I can relate to your fear. That is what kept me from quitting. Now that I have, I realize my fear was fed by the pills and was worse than reality.
Its like the anticipation of getting a flu shot for my kids. They freak out over it beforehand, and then afterwards, realize it wasn't as bad as they thought. No amount of reasoning would calm their fears, they just had to do it. Every year is the same! I was like that with quitting my pills. It wasn't a cake walk, but it wasn't impossible. And I am awash with relief now that the worst is over.
Try not to overthink it. Sincere wishes for the best for you and your family!
