Meerka yes things are generally on the up nowadays 
I still have bad days when nothing stays down and I retire to bed with sick-bucket, but these are less often. On most good days I still vomit a few times and have periods of intense nausea, but it's no longer constant which makes such a difference to general sense of wellbeing. If I plan carefully I can get out and about, see friends and enjoy life again. My worse times of day are 9am-noon then 5pm-late evening so I try to rest during these times and I pace myself, e.g. resting at home if I've been active the day before.
To all ladies currently suffering through the really grim stages, it honestly does improve at some point. Once the cycle of constant nausea-vomiting is broken and you're able to keep more down, you start feeling stronger (mentally and physically) and the bad days get easier to cope with, and eventually you get more and more good days. I noticed a real improvement around 25weeks but as Meerka says many people improve earlier, around 14-16weeks.
Daffodil how was the move? Try to take it easy and don't rush to unpack!
Mygreen good luck with your flight! Hope you get to Norway ok.
Chops are you still getting the pains? Have you been to EPU to get them checked out? I remember around 16weeks I had lots of crampy pains and stabbing type pains all over abdomen, my midwife said it was just the muscles and ligaments around uterus stretching, she said it can feel like period pain but not to worry unless accompanied by bleeding or intense 'crushing' pain. I also started getting Braxton Hicks (uncomfortable though not painful) around 16weeks, could it be that? Do go to EPU or GP if they continue.
MrsM about work...I went off sick around week 5 until week 13 when had a brief respite from vomiting (I attempted to return before that but felt too ill to function). I then relapsed badly around week 14 but felt so guilty I tried to stagger in most days. My boss was sympathetic and reduced my hours, but some days I was turning up hours late or leaving halfway through the day, this went on for a few weeks (interspersed with odd sick-days) until my boss called me aside and said I needed to stay home until the vomiting stopped. She also pointed out it wasn't fair on my team as they never knew when I'd be in or how long I'd last each day, which helped me see sense and took away the guilt at going off sick. So around week 18 I went on sick-leave again and am still on it at week 29. At some point I stopped expecting the HG symptoms to disappear and decided to take early mat-leave. So in total I've taken about 20weeks sick-leave.
Please don't feel guilty about staying off work. HG is an illness not a normal pregnancy symptom. Forcing yourself into work when you feel so sick is likely to make HG worse. I often think I should have just stayed on sick-leave from week 13 instead of feeling obliged to try and return, maybe then I wouldn't have relapsed so often in 2nd trimester! I strongly advise staying off sick until you feel strong enough and well enough to cope in a work environment.
About indigestion/heartburn... mine started early too! Gaviscon made no difference. I started taking 2 ranitidine a day (75mg tablets) that I bought from Tesco (Zantac is main brand in UK but Tesco and Bodycare do their own cheaper versions that's just as good)! This kept it under control for a while though by 20weeks the burning was back. I've resorted to Rennies in between doses of Ranitidine, which work well for me.
