I am. Not every day, but when I get a break for a few days I usually pay for it later and end up taking a few doses in a day. I hate taking it though because I get SO miserably constipated when I take it every day.
If it comforts you at all my last pregnancy I took it every 4-6 hours around the clock (and was still vomiting several times a day) and now have a healthy, happy, very "normal" 3 year old. It didn't seem to affect her at all.
