I am going to be different and start a new update date I had four really good days this week my o2 levels with o2 was staying up around 98 no matter what I did it was high and my pulse was low below 80 now my pulse is back up over 115 and o2 level is 93 I changed nothing so it must be the roller coaster effect you have been speaking of The four good days were great even my neighbors thought I had taken some kind of drug to see such a difference in my attitude on my bad days even my dogs want to leave home hopefully they will be become more infrequent I noticed that my wounds from my imitation of Rachel ray on Thursday have healed a lot faster and the black and blue marks from me running into the corner of the bed are healing a lot faster also now if I could learn not to be so clumsy all in all I saw the light and can't wait till I get there wishing everyone good health
