Hmm... Last year, when we were trying they put me on prenatal vitamins. I still have the Rx, so I'm still getting them. MAN, are my hair and nails doing great!!!
Funny thing - mine don't smell AT ALL. And since my sense of smell has come back with a vengeance since I quit smoking, you'd think I'd notice. They are so big they tend to stick on the way down, but they don't bother me at all otherwise (which is good, 'cause the Chantix DOES make me queasy).
...Someone I know said to mention peanut butter thinly spread on saltines, for the protein. Keeps the ol' tummy too busy to puke, I guess.
