I have been using my new Gazelle for a week now. It is very easy and fun to use, and for someone with as many health problems as I have, that is a plus. The problem that I have is everytime I use it, I am slightly dizzy and have a little nausea that subsides after the first 10 minutes, but if I stay on it steady for more than 25-30 minutes, I have about 3-4 hours afterwards of SEVERE motion sickness. I haven't been able to find any info about this, and haven't received any reply from his website. Has anyone heard of this problem? If so, did it subside in time, with continued use? The only other problems I have with motion sickness are when trying to read in a moving car, or after spending an entire day (more than 6 hours) out on our boat. I'm hoping it will go away, because I really love this machine. I've lost 4 pounds in the first week, and my husband has lost 6.
