1/ switching to a 3/32" singlespeed chain
2/ using a 1/8" track chain
3/ ss specific cog on the back
4/ go back to fixed you loser
5/ fit a mech you nerd
5/ any combination of the above

1 will make a tiny difference if you use a (less flexible) bushed chain, e.g. Wippermann 7R8
2 probably won't make any difference, except as for 1 if you get a bushed chain
3 a worthwhile upgrade, if the chain is falling off the sprockets
4 a tensioner will help by guiding the flappy lower chain run onto the sprockets on centre
5 yes :-)

Other things to check:
Is your chain tension uniform over a full turn of the cranks?
Is your wheel moving forward under the combination of your awesome leg power and the weak retention provided by a QR skewer?
