For me, adjusting to a CPAP was quite easy. Any physical discomfort (which was minor) was easily ignored in exchange for finally getting some sleep!

Others have complained that the mask is uncomfortable. I didn't have that problem.
Others may find the machines noisy (after all, it is an air compressor), but to me, it's relaxing white noise.

Give it a chance. After you've gone through an extended period of sleep deprivation, you may find that using a CPAP is a godsend. I did, and still do.
