1. I went to the local health food store with a bulk foods/herbs section and found vegetable-based capsules there. I got "OO" and ten capsules = 1T ES. So you will take 10 caps per ES dose with lots of water. They are pretty big capsules. A pharmacy might have them, or you can find them at iherbs.
2. What did the trick for me with oil was I think GRZ's suggestion to mix it with fresh, not bottled, grapefruit juice. This makes the mixture watery rather than viscous, which was the gag/grossness factor for me. Put the OO (Olive-Oil) and fresh juice (I used 1/2 grapefruit per dose, for a total of two whole fruits for the flush) in a lidded jar. (Chill first for even tastier mix...it really was not bad!) Shake hard. I try and focus on something and get all meditative about it and chug....
