I love this stuff! I had terrible morning sickness with my son, and they gave me zofran... which was horrible and I stopped taking it.
This time they gave me Diclegis, and I can actually function to take care of my son a bit! It supposedly takes a few days to build up in your system to really kick in more, but I've been on it for nearly 2 weeks and I see a major improvement while I'm on it. I haven't noticed any side effects except for being a little more drowsy the first couple days while my body was adjusting. I still get nauseous, still almost vomit and can start gagging- but overall it's waaay decreased. I notice if I forget a pill and it wears off, I have a horrible time back in crazy nausea- so I'm all over this thing! haha. Important thing to note is that it is time-released, so you take it at night to help with your morning, for example. Good luck!
