Morning, hope everyone's coping ok...
Had an awful day yesterday followed by a rough night, but feeling less queasy now. I can't sleep longer than 2 hours at a time, anyone else having this problem? Last night I needed to wee every hour or so, also very thirsty so kept sipping water, which then caused heartburn and vomiting, and more needing to wee. Getting in and out of bed is agony due to SPD. Also baby was very wriggly all night, he didn't seem to like me lying down at all so I ended up sitting up with a heap of pillows. I think he feels squashed in certain positions as he sort of hooks his feet under my ribs then wiggles his whole body vigorously side to side (which also triggers Braxton Hicks). As soon as I sit up or stand up he settles down
Managed about 4 hours sleep in total then got up at 5am and 7am to be violently sick. Every time I drink water it seems to turn into acid, even ice-cubes and ice-lollies 
MotherofPearl it made me smile when you mentioned Xmas, I've been thinking about Xmas a lot and looking forward to it so much! Baby's due mid-late Sept so he'll be around 3months by Xmas, I keep imagining him being fascinated by all the lights and tinsel and taking him to see the Xmas markets in his baby-sling. It'll also be our first Xmas as a married couple and first in our new home so a real landmark! I find it comforting to think about autumn too, walking through crispy leaves and mist and pushing baby around park in his pram. Normally I don't look forward to cold weather but this year it symbolises the end of HG and the start of motherhood! 
MyGreen I get sore eyes too though for me I think it's a pregnancy thing, I've found it hard to tolerate contact lenses since getting pregnant. I use sensitive eye-drops throughout the day which help a bit with dryness. Also I get bloodshot eyes when I've been vomiting a lot, I think due to tiny blood vessels bursting.
MrsM sorry you're feeling so ill and down. As others have said, it sounds like you need more time off. You might find a couple more weeks of rest then reduced hours make a big difference. Do you have any annual leave you can use up? I know what you mean about work being good for social contact and a sense of normality, but it's not worth risking a relapse if you're struggling and feeling exhausted. I found being off sick very isolating at first but I've gradually built up activities and social contact. Joining aqua-natal has been great for socialising even though I don't make it to every session.
Mellee yes I find sugar makes nausea worse too. It seems to make my heartburn worse which leads to more nausea and vomiting.
