Fernando -
Seems this has been discussed a few times and some say it has worked for them, others say no. I want to try it one time just to see but I haven't yet. The hardest part of flushing for me is the afternoon/evening when I'm hungry so flushing in the morning appeals to me. I would probably try to increase the effectiveness by lying down for a half hour or hour after taking the oil.
I hope you're feeling better soon. Keep us posted on how it goes. I'm interested to see how well it works for you.
