I just use that cheap ass body fortress whey isolate and it works pretty well. Typical day is something like...   
protein shake 
pack of precooked sausages 
2-3 deli meat sammichs 
can of tuna 
cheese 
can of peas or beans 
junk food 
another sammich 
c4- before workout 
protein shake  
some random large dinner (pizza, burgers, or pasta typically)   
I was using creatine for about a month and a half and drinking like a gallon and a half to 2 gallons of water a day but, I wasnt really seeing any results so i stopped taking it. I havent noticed any loss of size or strength since quiting it either.
