The smell of rubbing/isopryl alcohol?

from the time after I had my daughter in the hospital(almost 20 years ago)witch hazel has been a smell that is comforting to me, it's not quite as strong as alcohol. Also you could try chewing gum, mint preferably. Usually the first and last trimester are the times you feel the "morning sickness" the most. I thnk it is okay(as a last resort) to smell the alcohol and "thank you" for being a concerned parent. I HATE to see a pregnant woman light up a cigarette or DRINK alcohol.
