How often is "frequent urination for type 1 diabetes?"?

I’m doing a research project on Type 1 Diabetes (Juvenile Diabetes) and I need to know symptoms. One thing I need to write is how often "frequent urinaton" is. Like, once an hour, twice an hour, once every two hours, ect. Help, please! This is worth 75% of my overall Science grade. http://bit.ly/q1PvpW
