Jaw clenching

I have started to get jaw clenching on week two of 12.5 mg.
It’s not too bad, I can put up with it and it may wear off as side effects sometimes do.
I have had this side effect many years ago from prozac so I wondered if it could be a side effect of mounjaro and google tells me it could well be.
Wondered if anybody else here has had this happen?
I have been pretty lucky with mounjaro side effects so far. Only issue has been mild constipation which has been easily managed.
The weight loss has been well worth it.

Yes I had this, 2.5mg did it to me for 2/3 weeks after starting. I am still on 2.5mg (8 weeks in) and it's gone away. I'd love to know the science behind it, but I suspect it's something to do with dopamine/serotonin (since SSRIs / ecstacy in my youth did this to me too).
