Slalom, What is my Problem?

For anyone here who has an interest in ski racing, you will know that
there are many different types of it. I personally compete in Slalom
and GS type courses. I am relatively proficient in GS, having placed
15th in the state race last year, but for some reason, I just can't
grasp slalom. My problem with it is that in the beginning of each race,
I begin going down through the course, and usually do very well within
the first 3 gates, but after a couple more, I find myself getting later
and later with each gate. I tend to have to throw my skis right
sideways so that I can slow down and start fresh. This is the worst
problem with me and if I can fix this I feel that I will be able to do
very well with these races. What can I do to fix my problem and do
better on the course? Thank you so much for any input!
