100% I literally have to remove my wallet and put it in a front pocket or elsewheres when i drive the S

you may also want to find some inflatable lumbar supports that slip in behind the pad on the backrest. I have a pair of them and they are awesome! If you take you hand and pull the pad on the part of the seat where your lower back rest you will discover it is open all the way thru. You can slip something in there to support the lumbar part of your back more. Some guys just fold up a towel and slip it in there. I opted for inflatable supports. They are hard to find though. I looked at where i got mine and he does'nt make them anymore

 

Kidney stones. Drink a ton of water to pass them naturally or have them surgically removed

 

the newer models have more comfortable seat. the AP1 seats are not comfortable. I drove to canada and my ass almost went out.

 

^ well the OP has ap2 seats so

 

hmm, got to drive a friends ap2 and its much softer. I think it was 06.

 

Try eating more potassium, and stretching; morever a lumbar support would be beneficial; a member bought one from Honda Japan.
