ALPHABET GAME "T"

Hello and good morning Daily Vitamin readers, and Alphabet Game participants!

Today we are looking at the letter T, the 20th letter of the English alphabet (and the 20th day of our contest). Let's see if you know the word that completes today's sentence. 

Sentence: _____ as I may, I can't remember his name. And he's told me three times!

Do you know the answer? Here's a hint: it's part of an expression meaning "even with a lot of effort, a goal cannot be achieved."

Leave us your answer on one of our social media sites (Facebook or Twitter) and we will post the correct answer later. We will also include the correct answer in tomorrow's Daily Vitamin email

Good luck everyone!
