Can't guarantee you anything about the weight, but I had all the same symptoms except the extra periods because I'm in menopause. I can breathe through my nose for the first time in many, many years. My nose used to be constantly stopped up with horrible green stuff, which is completely gone now. Gas...I was so embarrassed when I worked as a cashier, because of the constant gas, and I was in pain more times than enough with it.
I'm so much better now, after one cleanse, and working on the second. Another thing that might help you with the digestive problems is coconut oil. It keeps things moving right on through and also helps kill the parasites in your digestive tract.
