I've started something that won't stop. Last night I crawled upstairs too quickly- because I'm a right eejit and didn't want to be seen by my 10 year old son! - got to the top of the stairs and stood up. Couldn't catch my breath, heart doing a dicky-fit and I ended up coughing and retching for ages over the loo. Lovely. Today I've found I can't stand up straight without setting off the cough-retch drama. Walking around bent over which is some control over it- but - well, it's not ideal. Anyone have any ideas PLEASE!
