diclegis for nausea/vomiting

Hey girls ! For those of you that have taken Diclegis I'm interested to hear your experience with it. It took a couple days for it to kick in for me but it does a pretty good job of taking care of my nausea - it's about 90% gone and I can eat almost normally now. It does make me a little tired but I can function. Worried that I am going to have a hard time getting off of it (heard this before)  and the only other 2 peeps I know that were on it stayed on it their entire pregnancy. Hoping I don't have to do that and can ditch it after the first trimester ! How about you ? Thanks !
