Was doing pretty OK, but was unable to solve 25A or be sure about the last two letters of 14D. I assumed it was the Cockney pronunciation of something, but never solved what the something was.
Found the needed hint on the first page here (though as usual, not numbered as if it is the first page). Thanks!
Had not considered the possibility that the "complaint" might be a medical issue, but that is certainly entirely valid.
There were quite a few very nice clue/answer combos in this puzzle.
I was not too enthused over 18D, since this "double definition" is really a 1.001 definition (the parts are essentially identical).
I did not understand how to parse 26A to get the first word of the answer. Any explanation would be appreciated.
