I'm in the "day too early" camp too, but I disagree that if you're asking, it's time. Some of us ask early and often, and don't always go forward. (ETA: I've been early and late too. Early hurts less.)
I was in a similar position with one of mine before Christmas. It felt like I was being pushed into it (pushing myself into it) because of the clinic's holiday schedule. She wasn't ready and neither was I. My vet advised that I not do it if I weren't ready. We tried another therapy and had success with it for a bit.
Re therapy: I don't know if it works for LS or not, but we've had some great success here with laser treatments. They kept a couple of mine going for quite a while.
I'm sorry about your IG.
