8x8 Sudoku Snack

Normal (irregular) 8x8 Sudoku rules apply, i.e. each row, column and region has to contain the digits from 1 to 8. Digits on a grey line form a palindrome, i.e. they read the same forward and backward. Digits on a thermometer increase from the bulb end. Digits joined by an X sum to 10. (Not all X are given.)
