Kiki, have you done any of the parasite cleansing? I'm wondering if your "hangover feeling" is related to other digestive problems. Have you been diagnosed with gallstones? Do you have gall bladder attacks?
Apologies if you've posted your background before. I'm a bit of a newbie to this site but an oldie with flushing, though my stone factory is still happily in production (been slack and indulgent the last couple of years).
Regarding the oil, I don't recall others trying walnut oil but Oleg tried grapeseed oil and got the same results.
Don't despair!! You'll find your way through this and it will feel wonderful when you reach the other side. Just think of Southern Belle among others!! :-)
