Taking Creatine/Maltodextrin + Protein

Anyhow out of school such as during the summer i would take 5 grams of creatine with 30-50 grams of maltodextrin immediately postworkout then take about 25-30 grams of whey protein 5-10 mins later. Anyhow now that i'm in school and working out in a school class, I don't have the time to take both of them at different times. I tried taking the creatine at the end of class then taking the protein when i got to my next class but the teacher didn't want me to drink it in his classroom. Therefore i drank it right outside his classroom and he didn't appreciate it either. Anyhow what i'm getting at is it okay to take the creatine/maltodextrin/protein all at the same exact time in one big shake like a weight gainer or something post workout or will the uptake of one mess up the other?
 
Sorry for the OCDness on this stuff.

Bump. Thank you.
