Try eating something that will stay the night with you , like hard cheese before retiring... Also as mentioned, warm up before turning in, jumping jacks running in place for a minute or two (obviously stop well before the sweat flows point).

Do not breath into your insulation (possible risk w/ pea pod)

Install your insulation and shake it out well before use... This allows it to attain full loft.

Come to the MAHHA at Gathland state park in MD next weekend...Will be 70+ of us there to a review and assist/council.
