They make wide / large / foam padded ones that might be more comfortable, or even having a few large ones over some kind of neck fabric to keep them from biting into the skin. Also some lumps where your cartoids are to make it more comfortable might be good.
They also have releasable ones if you know where to shop. Assuming you don't pass out you should be able to take them off if you change your mind quickly or if they aren't working.
Might be a good idea on the cheap but finding good ones might be difficult, and cheap ones might not be trustworthy.
One idea in the same line that might work is velcro cable ties. Pull it tight and then secure it down, you can always rip it off and make it loose almost instantly if you need to, plus hard for anyone to guess what they're actually for if you keep some around your usual places. Or maybe even cinching straps. But that's getting back into the night night method.
