Hi Saoralba, for 8 I have BERNE; for the 9th wiggle I have an alternative spelling for someone from Siam (but modern name) and 3 letter term for 'cook and serve'. Even if you have only the first 3 letters, the snake should be easy enough to find.
I think there are a couple of people on this forum who've said that they've finished. Once you can begin to fill up the grid, the process isn't that difficult, so long as you're careful and follow the rules. I'm struggling to find the time today, but will definitely come back to it...
