I have been using mouthstick for years, but last year the chemical makeup of the sleeves changed and I'm not able to use the new ones for more than a week. And one time I was able to use latex tubing, but I'm not able to find it anymore. Does anyone have any ideas?
Here is what the sleeves look like. http://www.4mdmedical.com/mouth-sticks-mouthstick-sleeves-fits-both-adult-and-pediatric-4-pkg.html#.U1XMX3y9KK0 Q
