Actually...you can...and you get what is called a Whitey.
I'm Lucky..I don't suffer..but hubby does.
His face goes pale and he gets a bit disoriented...and groans a lot....
Fastest anti-dote is a cold wet flannel around the forehead back of the neck...and either sleep or walk...
It is no Biggie if you know it might happen if you are being greedy....
...and start to feel a bit Flaky...
