Works great
Scent Name: Berry, Size: 100 Count
I have to use these for about 1/2 a year. I keep bronchitis and sinusitis from about Oct. to April every since I was a child. When I am suffering with these I can't breath through my nose, epically at night while sleeping and would wake up several times a night with dry mouth so bad ir was literally painful. My mom turned me on to these because she was using the with her CPAP. I sometimes have a bit of difficulty getting them to stay put but overall they are great. I have tried the OG, cinnamon, and berry. The OG have no real taste, but you wake up with a sweet taste in your mouth. I tried the cinnamon because I love cinnamon and didn't listen to the reviews stating how strong the flavor is, big regret, it's like putting two or three fireballs in your mouth, won't be making that mistake again. The berry ones are actually best in my opinion. They have a light berry flavor that isn't overpowering, isn't quite as sweet as the OG. Whichever one you choose you won't wake up in pain. I do suggest using only one at first as opposed to the two they recommend, unless you like waking up with your head on a water logged pillow. One generally gets me through the night unless my congestion is super bad, then I will sometimes have to use a 2nd one about 1/2 way through my night when I wake up for the bathroom and realize it's already completely dissolved.

Get traction in your life work
Format: Paperback
This book is the best book I've read this year, giving concrete ideas on how to get more, I do mean more, in your life. Whatever your passion, be it starting a business, or in his case businesses, hobbies, relationships.
One exercise Koch suggests is coming up with a list of your 10 best friends and rate them 1-10 (that in itself was fascinating) then put a percentage next to each friend. Are you spending the right amount of time with your closest, or more time with those less dear to you?
His many insights will lead you in new ways to think about your life, your business, your family and friends.
If you want to find new ways to think about your life, if you are in a rut and can't figure out what to do, if you are like me always busy and sometimes wondering am I doing the right things--this is a book for you.
Richard Koch has written on this subject before and this is the best book for the individual.

Interesting Follow Up to the 80/20 Principle
Format: Paperback
If you enjoyed the 80/20 Principle this is a good guide to applying it in your life. He does make some bold predictions like highly competent individuals will soon make public corporations obsolete. Some of this book is highly speculative and other parts are very practical. Luckily it is pretty easy to tell which is which. Very interesting book.
