My hubby was diagnosed with mild sleep apnea, so he's started using a CPAP. The question is- did it take you long to get used to it? He is not feeling more rested than he did. He is just as tired and he's been on it two weeks. It's a nuisance and he's not too sold on it. If he could just lose about 50 lbs. he likely wouldn't need it, but that's hard to do overnight. Any input?
