In this document (same one I sent you earlier with the O2 information), toward the end, there is a section headed "Treatments without O2." Some of them might help you. https://clusterbusters.org/forums/topic/6213-basic-non-busting-information/
I'm getting slammed for the second time today and that is unusual. Took a pill and did some very deep breathing. Earlier today did this and it really helped but right now, not working... was talking to a good friend and it started to hit me again....just don't know. My brother is sending me some O2 equipment and just wish it was here right now but just saw your post and decided to ramble on about my problems. Happy holidays and merry freaking Christmas...whatever. No joke take care.
