I'm Bulbar, not quite a year since dx. The first few months, during the night, I would get extremely dry. Bioteen was the answer. As things progressed, for the worse, dryness became a non-issue. Excessive Silvia and eventually mucus flow became the bane of my existence. Meds, patches and Botox (still in early evaluation) provided some relief. A desirable yet temporary 5 or 6 hours period of bearable dryness. However, a heavy mucus flow has since become a significant problem. Compared to the afore mentioned relief. It seems I always had a pool of fluids (mostly mucus) in my mouth.
The nebulizer was introduced with Ipratropium Bromide... 'seemed' to help, but not always consistently. Currently the Nebulizer, Scopolamine patches, a mucus thinner, Botox (1st round wearing off early as expected/predicted) and a silva reducer generate the much desired current dryness. That said... I'll take the dryness over the constant fluids any day of the week.
I'll be seeing my Dr. in a few weeks and hopefully we can come up with a promising mucus/Silvia remedy based on current experiences. Additionally, I get a second round of Botox also. This seems to be a constant state of experimentation.
