I am really struggling with this one and I think I will have to throw the towel in. I have filled most of the bottom half of the grid, but the top half is a different matter. Despite previous hints here, I still cannot solve 14 across or 22 down. I also need 2, 12, 23, 26, 27, 29 and 33 across, plus 3, 6, 7, 11, 25 and 26 down. Any hints would be welcome
