Scared is good Home studies are good too, you'll probably have 2, one to collect the data and then another one to try out whatever style of mask/nasal you choose. I used to work at Monash, it's really really sneaky but if you go to one of their CPAP clinics, then you can get masks and bits and pieces for free, ask if they have any old equipment, they update pretty frequently and they may give you tubing and bits. Plus extra info can be good too. Good luck with everything, all my clients found it pretty darn life changing Quite a lot of ppl also found weight came off just with actually being able to sleep properly, cos sleep also affects metabolism, hooray for no dieting!
