Thank you, Lori. I have my fingers crossed that Macdonald's may still have a source for the quinidine. We also used Macdonalds recently to get high-dose injectable vitamin B12 for Michael, recommended by ALS Worldwide. Had hoped it would have positive effect, but so far, no real evidence of any change. However, Michael started on CBD oil last week, and that has immediately reduced the muscle cramping he was having in his legs at night.
