pregnancy nausea medicine, 2nd month

My wife is pregnant, this is our 2nd child.

The problem now is that my wife used to have navidoxine in her first permanency and it was good enough to minimize nausea symptoms.

Now in the 2nd pregnancy, she is in month 2, and navidoxine is discontinued and I can't find it anymore.

The doctor now prescribed vominore, but this one is really tough and causes rough depression, dizzy feeling and exhaustion.

I'm interested to find anything that is better than vominore on any good online distributor.

So, I would like to have suggestions and recommendations for my wife.

Thanks,
