I would stick with this for a while longer. 20 days isn't really enough to give up on it. If you want to start experimenting with other stuff then start doing Liver Flushes and gluten-free while you're leaving it alone.
I can only tell you what has worked for me and that's japanese.
for more inspiration read over the posts of someone named "stealthmode". To be honest he seems a little crazy (maybe just funny?) but leaving alone seemed to cure him too.
he updated to 6 months which was pretty much cured.
