My DW has been struggling with hyperemesis, and for a while she was getting good relief from half a restavit tablet of an evening, with B6. Ondansetron and Stemetil were only having mild effects for a couple of hours, but with the Restavit she would go through the night, and up until about 10am without nausea or vomiting.

But then after a few days, the effect seemed to lessen, and it wasn't seeming to have much effect anymore. We're left wondering if it's just the body compensating for it, or maybe the effect was based on the hydration and eating levels? When it was working best, she was freshly hydrated from the drip at hospital, but eating virtually nothing.

Does anyone have any experiences on whether the effect of Restavit has changed since first taking it?
