Sleep tips when he's gone

Jessica
My fiance drives truck so he's gone all week long and only home on the weekends. I have a really hard type getting any substantial amount of sleep when he's not there. I usually sleep cuddled with his pillow but it only smells like him for a day or two at most. I would rather not take any meds to help me sleep because we are TTC. Does anyone have any other tips that might help?
