Weighted blankets are the BEST!!!
http://www.sensorygoods.com/ if you aren't fussy the clearance bin is the best! they suggest you get a blanket 10% of your body weight + 1lb
the discount code until the end of the month is SCHOOL this will give you 20% off even on top of the clearance price.
I have a 15lb and LOVE it! got a second as back up.
