I started vomiting 11 weeks ago, thought it was a sickness bug at first but didn't stop. Ended up in hospital on a drip. This has continued, I wake up, force myself to eat and vomit several times over a period of 4-5 hours until my stomach settles. If I don't eat every hour or so I get extremely shaky and lightheaded. The vomiting doesn't help the nausea. I don't have any other abdominal symptoms and I'm not pregnant. Prior to this I was taking no medication and was fit and healthy.
I have had blood tests, a ct scan and a gastroscopy and nothing has been found. They've looked for gall stones, ulcers, etc. I am taking lansoprazole which helps a bit but it stops me from sleeping. Omeprazole was worse with causing problems with sleeping. Also, as I don't have a diagnosis I'm not sure why an acid suppressant should help with vomiting.
Has anyone experienced this before or got any ideas?
