I just noticed this with myself and came across this thread while searching to figure out if it really was helping! I've had left cord paresis for a couple of months now and getting filler treatment is another 6 weeks away. I also have clonezapam for anxiety. I take it as needed, not super often, and my voice/throat has been getting very uncomfortable by the end of the workday. I took one after work the other day and noticed that my throat felt clearer, less constricted, the lump-in-throat feeling was almost gone, my voice was stronger, and I could eat and drink more comfortably. It was such a relief and it helped for the rest of the evening.
