Stretch a bungee cord between your helmet and the rear of your belt or seat. Gaff tape a padded bar across your biceps to rest your chin on. Get a whiplash neck brace. Attach wings with a lot of lift to the side of your helmet. Tie a helium filled balloon to the top of your helmet. Glue an angled mirror to your stomach or fashion some kind of para-scope, and just let your head hang. Denial. Learn to like pain. LSD. Have your eyes surgically replanted on the top of your head, or your spine reattached to the back of your skull rather than the bottom. Only ride in dimensions without gravity. Become a god and will the phenomenon of neck pain out of existence.

I would go for the handlebar raise. A lot of randonneurs ride with their bars at about the same height as their seat. It's a perfectly reasonable thing to do.
