Jason, You have been very helpful. Changing negative habits for positive ones is really the key. The meditation exercises were great. But the most effective thing is to have someone to talk to. Rarely do you find somebody who takes you by the hand and shows you a way out. My breathing capacity has increased and this changes my whole personality. My children came last night and they asked me whether I have done a face-lift. Of course, the skin looks much better without a veil of smoke and depriving the cells of oxygen and vitamin C. I also became much more assertive.
