If you are having to use a lot more of your asthma meds than what would be "normal" for you I would be seeking assistance sooner and not wait the extra week.

For my girls if we have to administer Ventolin 3 hourly or less we need to take them into hospital, and on discharge they have to be able to cope with four hourly and as you are stuggling to meet that you may need extra assistance, they may even do a chest x-ray to see what is happening. Pneumonia is rife this year, I have been blown away by how many little one's and adults I know have had it, we spent 5 days in hospital with DD2 2 weeks ag with Pneumonia, RSV and an UTI!

Take care of yourself and you have fought hard a bit of extra help may help you kick it for good.
