if I keep the heat pad on it till I go in the bathroom will I have to worry about the tempiture being to hot?
Not likely, but you can always check the temp of your sub just before entering the collection site. The other alternitive is to just use body heat as I discribe in the substitution guidelines linked to in my signature. You may want to try using only body heat with a 2oz bottle and water as practice.
One last piece of advice. ALWAYS crotch the sample before entering the collection site. You may be ask to empty your pockets by the collector.
Keep us posted.
