I'm exactly the same as you, and hate the sight of myself knocking back Coke! The fizzy seems to take the edge of the nausea though, so I'm on sparkling water/tonic water/soda water depending on what's in the fridge.
When I had severe MS I could only let an ice cube melt in my mouth and I also found I could tolerate very hot, weak, sweet tea if I sipped it. I think the object is to get fluids down and sometimes it is the extremes of temperature that are easier for some reason. I could also tolerate those mini milk ice lollies.
Know what you're going through here. I found (bizarrely) that milk was okay, especially full cream. But nothing is that brilliant. In first pg I went off all liquids altogether and just had to go with the flow. I only endedup with one filling after 2 pgs like that (and not being able to brush teeth properly either)
Using a straw will protect your teeth a bit. I found liquids more tolerable sipped slowly through a straw especially if I bit down hard on it at the same time
Thank you all for your replies - it's nice to know I'm not alone.
It came to a head yesterday when I was secretly swigging Coke from my handbag at a toddler group and peeling DD off who was shouting 'me, me' saying 'oh no dear, this is just for mummies' - I felt like people must have thought there was alcohol in it!
I have been out today and bought lemon barley water, orange barley water (stuff of my childhood) and Duchy Organic ginger cordial (which better be good given the price!) and lots of fizzy water. It feels good to have options.
I'm tempted by DeJaVous's ginger tea. I shall give that a go when it gets cold.
