Good grief, I just wrote my whole post and it disappears!
I too had the large 'put on a hook and go fishing with' kind and rid them quickly, in under a week. I used my own cocktail of Now Essential Oils (they say on the bottle not for internal use but I do with great success).
The cocktail is STRONG and I had to mix it with 20 oz orange Gatorade just to get it down and then anything I could grab as a chaser.
I started with smaller amounts of certain oils and then after 2-3 days really amped it up after I saw the results I was getting.
#1 Weapon of Choice -
Oil of Oregano - 3 drops to start then worked up to 5-10 per day. Strong stuff.
Oil of Anise - 5-7 drops
Oil of Cinnamon 5-7 drops
Oil of Peppermint 5-7 drops
Oil of Eucalyptus 5-7 drops, sometimes more. Strong stuff. Don't say I didn't warn you.
#2 Weapon of Choice - Tea Tree Oil
NOT FOR INTERNAL USE - USE OF YOUR OWN CHOICE
No one will tell you (no one I know) that it is ok to ingest. Google it and you will get pages of what a huge no no it is. I found ONE woman on a message board who used it internally for lupus.
I chose a day when I knew I was not taking any supplements, vitamins, herbs, anything! I used 1 drop of Tea Tree Oil in 16 oz of water. No bad reaction. In a few days I used 2 drops in 16 oz water again with no bad effects. I have not chosen to try any greater amount.
So in my cocktail I also added 1 or 2 drops of Tea Tree Oil.
***That is your choice. I do not make any recommendation.***
This is a very strong drink so you will probably want to begin with 3 drops of each, except the TTO. Shake your drink to mix the oils before drinking.
I recommend drinking the entire amount as quickly as you can. I try for 15-30 minutes at the very most. The faster the harder you hit them. And hit them you will! Also it is strong and tastes horrible and quite frankly you just want to get it over with.
