Hey Rainbowzz
I guess it can be difficult to say what is and isn't sh - I guess there is the medical definition and then there is the whole perception thing........what you are doing with your tongue feels like what I do with my hair, its not a major for me, but its still there, sometimes I am obsessive about it, sometimes it just doesn't feature in my life at all.

I guess the thing is to take care of yourself and if you feel its out of control or you need to seek medical support, then it is probably worth investigating further.

I soooooooooo understand the grinder thing - I'm one too, my dentist has to file my back teeth down once in a while cause I keep taking chunks out of them.

Take care
