I also gagged a bit the first few times I tried this. I then started with only 1/2 Tablespoon and worked my way up in quantity and time until now, it's usually not a problem.

I have read of some people using coconut oil, olive oil, etc. but for some reason they recommend the sesame or sunflower oil the most. I have no idea why.

I've been doing this about 3 weeks now. I've noticed that my tongue is very pink and healthy, my gums are too. I think my teeth have whitened up some and my sinuses seem to be doing better. Warning: The first week that I did this, I had a lot of mucus to blow and spit out. But that's been a really good thing for me - living in a bowl that collects allergens like Nashville does has taken it's toll on me and I'm very appreciative of anything that can help clear out my sinuses.

I'll let you guys know what other things I notice as time goes on.
