I started out with limb onset and developed Bulbar symptoms but so far haven't had any respiratory issues. I second what Nikki is suggesting, if you're having any problems swallowing have a feeding tube placed. I had mine placed early and am glad I did. I use it for 90% of my food intake and have maintained my weight and have added a couple of pounds, which is very important for PALS. I am still able to eat ice cream and other soft foods by mouth.
Secondly, if you haven't already done voice banking and still are able to speak start voice banking now. If you contact the Gleason Foundation they'll provide you with the voice recorder and set you up with a speech pathologist to walk you through the process. I banked my speech and was able to have it installed on my Tobii device for future use.
