Kathy,
Overall, it all sounds good. Refresh me...did you have 1 or 2 levels done? I didn't see it in your signature. Obviously, we had completely different surgeries, but I am 5 weeks post-op, so we are just one week apart in our healing. Who is following you for your aftercare? Sorry you are having some difficulty with sleep. Have you ever tried melatonin? When I am off my sleep cycle, I take it and it does wonders. I'll take it for maybe a week, to re-regulate my sleep, and then when I stop it, I have no problem sleeping through the night. Just a thought. It's over the counter.
All in all, you appear to be doing remarkable. Again, I think your young age is definitely working in your favor. Before you know it, you'll be power walking and enjoying a spring bicycle ride.
My best to you,
Cindylou
