Got prescribed Zofran

*sigh* I am always nervous about this because of the "Class action settlement" stuff you hear on TV about it. I tried really hard with the Diclegis but after a week it would stop working and I would have to bump my dose up and go back to being even more exhausted. I keep telling myself it's only 4mg and that I cannot go through this pregnancy nauseas and in a medicine induced sleep for the next 6 months... I have to be able to function. Anyone else with me on the Zofran train?
