I got tired of the expense of Dr wilson too.
I cured myself by changing to an alkaline diet of 80% alkaline forming foods and 20% acid forming. It changed my life completely after 2 years of hell.
I strongly recommend you read the 'The pH miracle' by Robert Young. So much of it makes sense and you can do as much or as little of his program to heal yourself. I only managed a 3 day cleanse (he recommends 7) but my body was ok with that. Over a period of a month i lost 12lbs, my body changed shape into the shape I always thought it should be!! I rise at 5.30am full of energy and enthusiasm for life again, can work full time and have started to exercise again. all in a space of 1 month.
The only supplements I take is a multi vit and multi mineral as i know I have lost bone density.
