Bought the large size as I thought I needed time before I can expect any change. I used to be so terribly bloated after a meal and experienced cravings heavily. However, it was about 2 weeks into detoxing that I started to notice change in me. The bloating and cravings were significantly decreased. In fact I also notice my weight dropped at least 500g less. My sleep also improved such that there are more nights now that I am able to sleep right away and can sleep uninterrupted into the morning. Now I'm thinking of buying even more SuperDetox jars to continue this till the recommended 3 months max detox period.
