There are other options.. I too have sleep apnea…depending on how sever it is there are other less expensive and more likely to use cpap use is very low among people who have apnea as it is stupid uncomfortable. Think half face breathing mask with tubes and wires.
There are dental appliances to help with mild cases. Also losing weight and if you can’t afford the gear sleep in a more sitting position as it stops the epiglottis from completely stopping breathing. I am not a doc and the standard caveat these are things that worked for me personally.
