I always take a goody powder orally, then wait 20 minutes to snort my pill. The asprin and caffiene in the goody powder open the vessels.
That's my ancient secret. I don't take goody powder daily, just the first 1-2 days I get my RX.
Don't use saline spray, that's just silly. Why would you dampen your nasal passages when trying to absorb? The best method is to clean your nose, insert clean straw, then snort the pill.
