When drinking the plenny shake I get a scratchy, itchy throat. Is this normal and is there a way to avoid it?
I get this sometimes if I don’t mix it well enough, I think it’s probably just some unmixed powder that forms into clumps and tickles your throat on the way down. Try mixing it longer and harder and make sure to put it in the water before the powder.
Great tip from @Sewil!
You can also try letting it sit for about half an hour, so the water can absorb even more of the powder to make it even more smooth
