After the episode of letting pregnant women take a drug that caused their babies to be born deformed, it is better to be safe, and test the drug well before it is allowed to enter the market place. I am just thankful that I was not born earlier, when there was no treatment for Parkinsons symptoms. I do not want to take any drugs or treatment that has not been tested well enough. Any woman with a deformed child will, I am sure, agree. Billy Baird ([log in to unmask])
