I'm so glad you're feeling better, Jayne! That's great to hear.
Yeah, the obturator gets pretty yucky, huh? I take mine out and wash it three times a day (mostly rinse, full wash once a day, actually).
So you're 8 treatments done - excellent! Prepare for some sores yet to come -- get Boost or Ensure or Carnation Instant Breakfast VHC (can order through Amazon) to supplement your food intake. Good luck with everything!!
