Sneezing failure waiting to happen

 I work on my laptop on my lap with my left arm tucked next to my leg. My large mug of coffee is on the side table next to me but a lot of the time it is in my hand drinking since I'm consuming the 12 cups in one pot on a daily basis. So far I've been extremely lucky that I haven't had an explosive sneeze with no warning as I'm drinking the coffee. I did once sweep my complete dinner setting to the floor with a sneeze. I was trying to relax/straighten my fingers by placing them on the kitchen table.  Food and milk went flying, broke the plate.

Multiple steps needed:

1. Set the coffee down without spilling.

2. Work my way thru the various wires that are over the left arm, power cord, new corded keyboard, power supply to smartphone.

3. Grab the left arm and forcefully hold it down.

So far I haven't had my laptop get launched across the room or sprayed coffee everywhere.

I see nothing anywhere on fixing these involuntary movements: sneezing, coughing, yawning. My left arm flies wildly on all these.
