Walking vs lying down

Did anyone try walking after taking the mixture of oil/lemon juice/grapefruit instead of lying down?
At least one method recommends walking for 1-2 hours right after taking the mix.
Walking and lying down without moving seem to be so radically different.
I tried lying still but I think that walking (I have a treadmill at home) is better for digestion and downward movement of the mixture.
Does anyone have any experience with it?

Also, did anyone try apple or pineapple juice instead of citrus? I am allergic to citrus so I don't want to overburden my immune system during such a major procedure. If you tried other juices did you get good results?
Thanks.
