I respect that you have taken a decision not to take any meds. I do not believe you are being selfish and you are trying to do the right thing for both your son and yourself. I also think psychomom is right about your family and friends. They will hate to see you in pain and want you to be around as long as possible. I am really pleased that you are trying to live healthily and look after your health to the best of your ability.
However please don't give up on there never being a new and effective treatment for your genetic condition and rule out ever taking medication. God can use doctors to help people. Medicine is continually advancing. I don't know anything about OI. However I wanted to share something in regards to another genetic condition I am more familiar with Beckers Muscular Dystrophy which is similar to but less severe than Duchene Muscular Dystrophy (DMD). In Europe now there is the first licenced drug treatment for DMD Ataluren (Translarna™). In Duchene Muscular Dystrophy there is a problem with the Dystrophin gene meaning that dystrophin is not made or not made properly. If there is a premature stop codon caused by a point mutation Ataluren makes the body ignore the stop codon and make a more normal copy of the dystrophin protein. This drug is also suitable for certain types of Cystic Fibrosis. It is so new NICE in the UK have not approved it yet. Also my interest is that it may be suitable for certain types of indivuals with Beckers Muscular Dystrophy which my husband has. The reason I am mentioning this is that I strongly believe there is going to be a proliferation of treatments for genetic conditions.
