I have just found cot instructions f you need them!! email me if so x
Staryeyed - Maxolon (as metoclopramide is known) is very very good at stopping vomiting. It also seems to help with nausea.
The Dr will be concerned if you aren't able to keep up your fluid intake which is why they have prescribed it.
I took it a few times when pg and also had it injected (intramuscular - ouch) one time to kick start me into eating something.
I used lesser drugs mostly - cyclazine is often prescribed, stemetil can be taken as supposiories (I did this as couldn't face anything by mouth) and phenergan is extremely safe and very commonly prescribed. This mainle helps with nausea and is used in children for travel sickness.
Meto. is a strong one so you might like to ask for an alternative which won't be so scary for you! And save the maxolon for when you feel really awful, which you might not.
Also try to keep up fluids as being dehydrated even just a little bit can make nausea much worse.
I found that after a night of sipping milkshake with ice cubes in, I actually felt more able to eat something as my fluids were good. As long as you can drink something you will be Ok and baby will be ok.
