I thought my level of morning sickness was normal until my GP & Ob said I had it pretty bad

... I had it for 2mths from 6wks of my pregnancy & again at the last 2wks of my pregnancy.

I would have nausea 24hrs of the day. Go to bed with it & wake up with it. It never escaped me !! Just to have a shower made me feel nauseous at the thought of water running on me, how strange.

I could only stomach oranges, red rooster chips and zooper doopers (ice pole thingys) & the only lemonade I could drink was the Kirks label, LOL

... Though I never ever vomited, ... ah, not me ... I had it at the other end. I would have the runs 6 to 8 times a day. If I went out I couldn't be far from a toilet.

To answer your question ... I don't know whether they do work cause by the time I took them I was pretty much over the morning sickness

Anything of Ginger ... & Rennies tablets didn't work for me either
