Re: Master Cleanse
I know what you mean about all the arguments around water...it leave a person wondering which kind to drink.
Search on chetday.com for a fairly balanced view. In particular, see "Why I Say No To Distilled Water Only": http://chetday.com/saynotodistilled.htm
As far as fasting, I have tried both, and sometimes alternated distilled water until noon, my normal filtered water the rest of the day. (It gets to be a pain buying all those gallons of water;)
If you read about 'The Water Cure
,' Dr. Batmanghelidj, says get whatever water you can. He used plain tap water when he did not have access to purified water and still had success. I think this puts perspective on things.
Don't second guess your water selection. Do some research and make a choice knowing that you are doing the best you can with the information you have at this moment in time.
As far as Propecia, you have to make your own call on that. If it wasn't a 'necessary' medication, I personally, would not take it.
All the best,
