I use distilled water for my CPAP machine. I was told you shouldn't drink it by someone, I forget who. But the web link I found said no real harm but it's not the best for you.

You can drink distilled water, but it does not contain the same minerals as tap water. It may also have a flatter taste and tends to pull minerals from whatever it touches, including plastic bottles.
Common uses for distilled water
Because distilled water has been stripped of its minerals, it’s often used in cars and household appliances. Here are a few common uses:
- steam irons
- aquariums (mineral supplements should be added to the fish food)
- watering plants
- car cooling systems
- laboratory experiments
- certain medical devices, such as continuous positive airway pressure (CPAP) devices for sleep apnea
Takeaway
Distilled water isn’t likely to dramatically improve your health, but it probably won’t hurt it either. If you don’t mind the taste and you get enough minerals from a well-balanced diet, it’s fine to drink distilled.
You can also use distilled water around the house. Pour it in your iron or your car’s cooling system to prevent mineral buildup. Or, use it to water your plants or fill your aquarium.
