I've a plump face to begin with, I can't say it made much of a cosmetic difference, possibly made my face appear a bit longer.
The botox dose was so low it didn't have much effect on my jawline, but it did "reset" or "break" the clench-pressure-clench loop which you seem to also suffer from. I found that if I tried to clench my jaw, I couldn't impart the same force as before. The relief and improvement was almost instant. It was injected in about 5 places either side.
If you look up botox + TMJD or TMD you can find info on the medical aspects of botox in the masseter muscles.
I would definitely look at the pillow you use also, if it's too firm it will influence your jaw position when sleeping. I hope this helps you and others reading this!
