I'm left-handed, and [writing] dyslexic. To be able to form any repeatable small pattern shapes with a pen (or pencil) such as letters or words, requires me to grip it with the force of an industrial press. Even then, I have to tense my hand, wrist and arm muscles just to write 'neatly'. As you can imagine, I don't ever write long essays.

Rubbery grips don't help me or hinder me, but I do tend to prefer them over hard plastic pens, not sure why.

I used to think 'Hey, we all use keyboards now, my failure to be able to write words wont be a problem anymore', but no... the world is now telling me 'tablets and pens are the future'. Not for me they are not; I have yet to find any handwriting recognition algorithm that can decipher my scrawl. In fact the lack of traction on the glass tablet screen makes my writing worse. :(

Several of my relatives have this sort of issue (minus being left handed). Some of them have seen some improvement by taking B vitamins and magnesium supplements, a thing that was tried due to information from a study. It isn't a cure, but it has made things more bearable.
