There are four weeks in a month. You lost 34 pounds in one month? That means you lost over 8 pounds each week. A doctor would question that kind of weight loss. It's likely to be unhealthy. I question the safety of that kind of supplement and that kind of weight loss.

What is a safe rate of weight loss and why?

'Nine subject groups derived from five published reports met the criteria for inclusion in the analysis. When the results of these groups were evaluated statistically, a curvilinear relationship between incidence of gallstone formation and rate of weight loss was demonstrated. The relationship was best described by an exponential regression curve, with an adjusted r2 of 0.98 and a dramatically increasing risk of gallstone formation at rates of weight loss above 1.5 kg per week.'

Gallstones can be very uncomfortable.
