A few days ago, someone passed a message to me via Janet Paterson from someone hoping to use my program to analyse and optimise levodopa dosages. I put it to one side, planning to get in touch with the caller , and it must have been buried under a pile of pig droppings which are currently spoiling the list. Would the person please email me at the address below, and we can get going to help your friend Regards -- Brian Collins <[log in to unmask]>
