Everything?..
Quebec,
First of all, welcome to the board!
What seems to be the problem w/ the waist?... Are we talking about fat or loose skin? Maybe bloating and edema?...
Couple thoughts.
Prep. H for loose skin. Thiomucase, if you can find it.
Try yohimbine for fat burning. You could even try a local application with a transdermal carrier (DMSO is a common, but smelly one).
Maybe you're bloated from milk / dairy?...
Are you constipated?... Perhaps you have the beginning of an impacted colon.
Are you using anti-e's?... These will not only help prevent sides, etc., but will help w/ fat mobilization.
