when im buy myself i sprawl out and sleep.
when im with my fiance we hold each other untill were about passed out then we sleep with our back touching in fetal position.
Honestly, I'm not a sleep in type of person or much of a sleep person at all, but when I do manage to get some sleep, I'll usually wake up in the middle of the night and curl up behind my gf and give her a hint of whats up after that, I usually toss and turn all night, and get up to take a leak about 2 times every night or my kid keeps me up all night because she wants to play, and watch tv at 4 o'clock in the morning.
