Lots!! I ran out of antisickness tablets the other day and so far today I've been sick 8 times since I woke up and when I'm not being sick I'm feeling sick and my mouth is doing the horrible watery thing
Thankfully my OH is picking up my meds from the doctor for me in a couple of hours
When I'm on the max dose of antisickness tablets I'm usually only sick 1-2 times a day and feel sick for part of the day.
My Tips:
1. Sip drinks little and often through the day rather than trying to drink a reasonable amount in one go.
2. Keep dry crackers or plain biscuits next to your bed and eat a couple when you wake up before you try and get up. Also if you wake up in the night to go to the toilet munch one if you are awake enough.
3. Try the acupressure travel bands that people usually use for seasickness
4. Eat small amounts every couple of hours rather than 3 big meals. Try to never go more than 2-3 hours during the day without eating something no matter how small that something is.
5. Try ginger, it doesn't work for everyone but it is worth a try. If you don't like the taste try sniffing some ginger essential oil.
6. Try eating and drinking at different times. It might not work for everyone but I cannot drink at the same time I eat without it coming back up.
And the most important thing to concentrate on... as horrible as the sickness is, for the vast majority of people it is totally gone by around 14 weeks
