Hi Erica,
If you're able to eat quickly, DON'T! Pace yourself, try not to talk and eat at the same time. (or while reading, on the computer, etc, CONCENTRATE!) I was advised not to use a straw as it delivers the drink too quickly. (Some people have been advised to use one, and at first I did, until I ended up with pneumonia, and the SLP had a conniption when she learned I was using a straw)... Supposedly tilting the head down and tucking chin in helps, but I've not had a lot of success with this maneuver.
The thing is, you could have several combinations of scenarios. One is that your vocal cords might not be closing tightly, or your epiglottis moving into place. Another possibility is the sphincter muscle at the top of the esophagus does not open every time, and food or liquid is stacking up.
Also, miscoordination, such as spillage down the throat before consciously swallowing.
If it were just thin liquids, then using a thickening agent would help. But, some people dislike having to do this, so adding it as a step without really knowing why you're having a problem might be just adding to your overall non-enjoyment of the
ALS Experience, if you know what I mean.
Absolutely call the clinic you're seen at, and tell them you've noticed a change with ease in eating and drinking, so they can schedule you for another swallow study.
