I believe the first priority right now would be to get those bowels moving as otherwise you are becoming toxic. Blessed Herbs is a great product, though pricey.
If you eat 2 quarts
of airpopped, hopefully organic, popcorn with minimal to no oil or butter (maybe some coconut oil) and a small Watermelon
all in one day you should start getting cleaned out due to all that roughage for one thing.
Taking 2-3 capsules of magnesium before bedtime has helped many people. I personally think brand can make all the difference and have found Twinlab (cheaper at places like Vitacost & iherb) to be very good.
Some people really like Oxypowder
but I have found that it seems to deplete my electrolytes or something because it made me feel very tired after a couple of days.
You can do maybe 1 high enema a week w/o getting dependent on enemas, and low enemas (2 cups at a time) will cause no dependency so use as often as helpful. Be sure to eat acidoophilus yogurt to replenish good bacteria. Dannon sells this in the plain, usually non fat, no Sugar
etc. added version.
Some people use cascara sagara and it is effective, but you can get dependent on it. One way to counteract that dependency at least somewhat, if you find it's all that works, is to not take it every day.
I agree with Sunflower that you will not get far with a cheapo parasite
cleanse and that you need to be very agressive - and persistent maybe for months! - in killing them. After that you need to do maintainence. I do it daily.
