Use at least 1/2" light weight sheetrock with glue and 2-1/2" screws not nails.

I would have no issues using 1/4 and have many times. I forget about the lightweight stuff though and might side with Joe if you can afford it. It will be easier to handle. A 1/4 4x8 sheet is going to weigh about 38 pounds and the lightweight 1/2 will be about 41.
I would not glue drywall though.
And don't forget you will need to extend any ceiling boxes, cold air returns, heat ducts, etc.
