Im in a similar boat been waiting for awhile for CPAP…my OSA is more positional (supine 39AHI, side sleeping 9)…so in the meantime I tried side sleeping which helped a bit(lookup BOB AND BRAD on youtube they have great videos on how to get comfortable side sleeping)…snoreRX (didnt work)…Tongue Retaining Device, i coilsnt get used to it but may try again, it might help you if your OSA is a tongue based issue (amazon has them…also lookup Tongue and Throat exercises for OSA online lots of good resources…Another great resource is Vik Veer on YouTube, hes an ENT who offers great insight into OSA and reviews various treatments. Goodluck, be well!
