Using the syringe method! Any success stories or helpful hints?

We have been having lots of issues doing it the natural way because of medications but this is working great for us so far! Much better being inseminated everyday in my fw then twice or three times all month and hoping for the best! I'm worried about the speed of putting them in a syringe might damage them but I know I'm prob being paranoid lol any tips or tricks or success stories? We are also using preseed and I put my hips up for half an hour afterwards
