Kiki, Interesting about not using them while pregnant. When I was pregnant I didn't have morning sickness, I had 24/7 sickness! Anyway, I lost 15 lbs. the first 5 months and my Dr. said no to meds but did recommend the sea bands. I wore them all the rest of my pregnancy. I swore by them. (My son is 11 and maybe things have changed since then.) I would certainly tell everyone to ask their doctor.
