I know how u feel. I had that prob. Still kinda do. Try juice & sip it slowly. The thing I was greatful for is that water comes back up easily & doesn't have the yucky taste or smell! Now cordial & juice is alot easier, water is still hard to drink though. Normally I love it. I didn't like it too cold either for some reason.
If you drink it slowy - small sips, & experiment till you find something u can drink. The lemon sport drinks are OK. Or cold water with a slice of lemon in it was good with my first pregnancy.
