I too had a slow start. Coughing up gunk, but like trapper says, better out than in.
I used a teaspoon and could only go for about 5 minutes at first. Now I am using flax oil and going the 20 minutes! Loving it too.
Give it 2 weeks to a month and just build up and do what you can each day. I used a timer and challenged myself to a few more minutes each day. Now I set the timer and away I go.
Let us know how you are doing.
PS If you really don't like the taste, pick up the apricot oil. I found it in the personal care section at my health food store. The bottle says for internal or topical use. It is so mild you can't even taste the oil. My kids will take it if that tells you anything. Even the grandkids. They think it's medicine ;). I just pour a teaspoon and down the hatch.
