Is rebound expected after discontinueing clen use? Rebound in regard to fat storage or slowing of metabolism? I just started some low dose clen today and will be used for only 15 days prior to a vacation, just adding it on to help with some last minute water loss and fat loss around belly. I plan to stop taking it the day before our trip. Just wondering if it is common to see a rebound in anything after coming off that i should keep an eye out for?
