I think for starters you need to psych yourself into appreciating the olive oil for what it can do for you. You might have a little talk with your nose and with your tastebuds and with your stomach to value your flushing routine. Some visualization would help too.
If this sounds strange, just do it and you may find that it works. You will need to be gentle but persinstant about this process. Give yourself enought time until you feel confident that you are in sinc with your body.
You may want to stay away from olive oil other than for flusing for now.
When you are ready again for another round blend the lemon juice right in with the olive oil while you think how good this will be for your body.
