I do wonder if my expectations are too high. This is the second anti sickness medication I've tried. I'm now 14+ weeks and despite being on renedine (2 x) and prochlorperazine maleate (3 x) I still have retching (daily)and a vomiting episode yesterday. There has been a massive improvement but it is still happening. I'm also scared that the more main stream drugs that don't work the more chances are I'll end up on something untested or something. Silly I know.
