This is crucial as Jing and Yin deficiencies can not be replenished only by abstaining, breathing and exercises (Yang is much easier to replenish by means like qi gong, etc.). They are substances and other substances (food) must be refined to replenish them. First step is leaving the addiction but the damage is done and must be reversed. I will also put some links to specific herbs You can buy over internet (which address the issues): http://www.iherb.com/Planetary-Herbals-Rehmannia-Endurance-637-mg-150-Tablets/1582 http://www.iherb.com/Dragon-Herbs-Rehmannia-Six-Combination-500-mg-100-Veggie-Caps/33147 http://www.iherb.com/Dragon-Herbs-Super-Jing-500-mg-100-Veggie-Caps/23132 For tonifying Yang (only after tonifying Yin!): http://www.iherb.com/Dragon-Herbs-Dragon-Jing-500-mg-100-Veggie-Caps/22355 In IHERB during first order type code: KIQ663 to receive about 10$ discount. They send packages to Europe and I have never had any issues with customs (just pick the cheapest package option - standard post). It takes up to two weeks. There is also a great store in UK I found lately: http://www.healthylicious.co.uk/ They have pretty big choice, just search for the formulas I wrote in former post. Also remember the diet (I already wrote the specifications) and rest!
