I have been feeling anxious during the COVID-19 pandemic and I thought this might help.  I ordered the 20 lb blanket, even though my size and weight said I should get the  15 lb.  Well 20 lbs is heavy!  I initially regretted my decision.  But, I made myself give it a couple of days.  I track my sleep on my FitBit.  As of last night (day 3), I had a solid 5 hours with NO waking up before I had to use the bathroom.  I am sold.  I still think I probably should have purchased the 15 lb but this is really working for me.  Again, give it a few nights.  It takes a little getting used to.  I highly recommend the product for its intended us and for the quality.
