How much dextrose with creatine?

[Barry Fountain]

Hi, I am currently taking 5g creatine before workout, and 10g post. I mix each of these portions with 30g of dextrose. for the post workout, i also eat a banana for extra spike. Does this sound right???

5g post would suffice. 60g total dextrose is ok.
