Me and Cutler usually mix our creatine with Crys'

... but any high GI sugar works. Your dext is a good bet, but Gatorade works fine too... I use HFCS sometimes. Just take at least 5g sugars/1g of creatine you take... so 5g creatine with 25 or more grams of high GI sugar.
That info on taking 40g/day is kinda nutty. You want to take 5g/day
every day whether you lift that day or not. You need to maintain the levels in your blood and muscles. On days you don't lift, you can take it any time, but I'd avoid taking it on an empty stomach or before bed. It irritates the stomach for a lot of people. Some people (myself included) also load it the first week by taking it at 15-20g/day in spread out portions.

I take it only for 6 or 8wk at a time and then at least a month off of it since that works and is known to be safe. Something like this...
wk1: 5g with 30g sugars 3 or 4 times each day
wk 2-6 or 8: 5g with 30g sugars each day (post workout if it is a gym day)
