Yes I am huge grinder and have been since I was a child. I've also become a clencher 24/7. I strongly urge you to get yourself a nightguard prepared by the dentist so that you don't ruin your teeth and need cosmetic work done.
Make sure it fits properly and and comfortably. I have had several that were not aligned properly and it messed up my bite. I wear mine usually 24/7 as I am so used to it and have been clenching in daytime.
It will be worth it I assure you!!
