twice sometimes three times a day (one in morning before school, if I get dirty at school then I take one when I get home - also helps to get gel out of hair, then once at night if I'm dirty again. What can i say, I like to feel clean). Three times a day is kind of extreme but sometimes I do it just ot get warm... my mom is cheap and keeps the house at like 40 degrees in the winter time... I can go outside and it's always warmer even though it's raining.
