I didnt think they were working for me, had to have 2 days off work as was just gagging all the time, then I worked out that for me anyway, I need to actually eat something first, then they will stay down and they really work! still not 100% but heaps better!!
I was taking the pregnancy and bf mv as well, but I just cant do it, they make me ill, I was talking to some other people the other day and they complained of the same thing, I was glad as I thought it might have just been my imagination!
