Here's a little trick that I use off-shore for the roustabouts and floorhands, but I modified it for you since your @ home.
Get 2 tumblers half full of ice. In one, fill with water and let stand for 5 minutes. Submerge finger in ice water fo 10-15 min. , repeat
2 x day (twice daily) for 3 days.
Since your @ home, fill 2nd glass with favorite adult beverage. (I prefer a single malt scotch) Enjoy!!Oo.
