I don't know if wearing some kind of thin 'mitts' at night would help
(fingernail damage at bottom). Pharmacies or Paint stores sell thin 'rubber'
gloves in 20? packs and are relatively cheap (I know a house painter that
uses them rather than spend 20 minutes washing his hands at end of the day),
or as it gets Cooler there may be thin Knit Mitts on sale soon.

  WRT the tooth or tongue damage, a quick fix (for tonight), might involve
going to a Hockey or Soccer sports shop and buying the kind of mouth guard
they sell for Goalies.  (Plastic and covers both top and bottom teeth.)
Cut it in Half horizontally since you only need cover the Top teeth to
prevent Tongue and Tooth damage from Nocturnal seizures, now you have **2
for under 20 dollars.

   Since you're in Canada, if you have a Dental Insurance Plan, or even if
you don't, the Best solution, *I* think, you can get a Quote from your
Dentist for.   They do an Impression of top and bottom teeth, and make an
'Occlusal Splint', a Soft Plastic cover that slips over the front top teeth
at bedtime.
  Ballpark-- Fitting and Lab costs, with first Splint, are about $160-200?
Usually they can make a Second splint and sometimes a third from the
Imprints at about $60.    After 2 years or so they'll want to do new
impressions.
(Write me if you want detail on how they do Impressions. Nothing GROSS
involving drills Needles etc you might associate with a Dentist, but I would
have preferred if someone told me in advance about how I'd spend 20 minutes
waiting for the 'rubber impression' to harden when they did the fitting.  In
6-10 days they get the Professional fitted version that I prefer.

  I'd recommend the Latter as they are as thin as a Dime and within one
night you won't notice it's there.   IF you have a lot of nocturnal
grinding, you might need the second one in about 4-6 months, otherwise mine
last 15-20 months range.   They come in a small plastic tote case for travel
and storage, but don't Glow in the Dark :-<   I first thought they'd be good
for Halloween, but there are no fangs on them...   G./

Howdy Chris!

As a matter of fact, it means"

"Don't let the bast*rds grind you down"
(left out the "a" in case you have a profanity filter)

Very appropriate when talking to my fellow epileptics!
