both husband & myself use one. Ours are both quiet when we are wearing them. We both have our machines down lower that night stand. Mine on a small footstool next to night stand. (not in my way when I get up) Husband's on lower shelf of his table. Both use mask that goes over nose only. And we tuck our hoses over and around our pillows. I move around from side to side without any trouble. Our hoses must be at least 3-4 feet long. At first I had indentations on cheeks from the straps (chubby cheeks) but had scraps of fleece, made a tube large enough to fit over straps and no more marks for entire day. We both had no trouble adjusting. But I also know from other friends that there are many different kinds of masks and machines. So shop around if a change is needed. We both have the heated machines. Mine is as low as possible during summer and # 1-2-3 for winter. The humidity levels may have to be adjusted from time to time to avoid humidity in hose. And don't forget to adjust the mask for snub, not tight, fit. Check insurance for replacement masks, too, on a regular basis. Good luck and don't give up.
