This is great advice, thanks. On that subject, I use CPAP since 2008 but I occasionally did not use it for intervals up to a week (for example, when I traveled I would not bring the CPAP with me). It turns out I had an episode of atrial fibrilation (the heart beats with a weird rhythm) due to a few factors together, but the major one being the lack of CPAP usage. It was scary and I spent the night at the hospital. The doctor explained me that this condition can be caused by low levels of O2 while sleeping, which is caused by apnea.
