These are excellent tampons and they protect very well. As to the length of time they last, it depends on your flow. I've seen times when I changed them every hour and I've seen times when they lasted 4 hours and then I changed them because I thought that I should rather than them having been used to their maximum absortion capacity.
I strongly recommend this product. As to the length of time, you'll have to discover how long they last for you and your particular bodily needs. Amazon sells a selection of 88 including regular, super, and super plus absorbency for $18.41.
Also, a selection of 36 each for $10.19. http://www.amazon.com/Playtex-Gentle-Glide-Tampons-Unscented/dp/B001AIJZQ6/ref=sr_1_7?ie=UTF8&s=hpc&qid=1225637246&sr=8-7 Walgreens has a better price of $8.99 for 36. http://www.walgreens.com/store/product.jsp?id=prod2340846&CATID=100230&skuid=sku2340324&V=G&ec=frgl_589508&ci_src=14110944&ci_sku=sku2340324 AmericanRX has 18 for $5.44.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
