I use a "forehead support apparatus" nearly every time, cold-sober or otherwise. That apparatus is my free forearm, which would otherwise be unused in this configuration.
And for those worried about getting a dirty forearm from the wall, aforementioned forearm is then be held down over the exposed bits of trousers when completing the operation, thus preventing unsightly splashes on one's clothes.
And finally, the very useful forearm gets rewarded by being washed off with the hands at the end!
The inventor assumes that the user requires vertical support, yet is capable of conveying his own laterally unstable body to the device in the first place. A brief trip to the watering holes late on a Saturday night will convince the inventor that this is rarely the case.
I got VERY drunk once about the same time as you, Erebus, and like you have not repeated that experience.
However I have got "comfortably numb" a few times since then, but even when not in that state, my height makes a bit of vertical stabilisation desirable when emptying the bladder.
And for that reason I must take issue with this design. The stabiliser looks to be firmly attached to the wall by lugs 20 in Fig 1 above. I'd suggest that having the stabiliser mounted on a rail so that it can be moved up or down to suit the user's precise forehead dispacement from the floor would render this device applicable to a far greater segment of the male population.
Excuse me now. I'm off to the patent office....
I got drunk once, in 1972. Horrid experience that I have not see worthy of repeating in all of these years.
If they modified the device and put a taser electrode into the head rest, then I would help install these everywhere.
Anyone that gets that drunk needs to be shocked out of a very bad lifestyle.
Just my opinion.
