Still waiting nervously for the post to come.
I found some small bore soft plastic tube in the irrigation 
section of a home improvement store. 
The tube fitted snugly over the syringe outlet. 
I held the other end of the tube over a flame to burn off any rough edges. 
I tried it out with some water, it worked well. 
My waistline has expanded with the years and some positions are rather hard to achieve. 
With the tube on I can inject lube in comfort. 
Been reading the Wikki and other postings and blogs.
