Kim,

Sorry to hear about what your dad is going through, but looks good that he has been clean for a little over a year. Can't help you with the botox info, but my sister used a portable suction machine the entire time she was going through treatment. It was a life saver, and only cost $30.00 a month to rent. It can be carried anywhere you go, is maybe 5 lbs. or so and can be recharged periodically. She was unable to swallow and use to vomit quite a bit, and there was always concern that she would aspirate, the portable suction machine really made the situation so much easier to handle. It is a little loud when in use, but worth it's weight in gold. Hope this helps in the short term until you find out more about the botox.

Best to you and your dad,

Nancy
