put a water hippo/brick/other non disolvable heavy bulky object in you cistern to reduce water used for each flush, or buy a
http://www.interflush.co.uk/ system, says it cuts your flushing water in half. then flush after ever bowel movement. is your toilet very old? maybe the poo sticks because the shiny bit of the pan has corroded and is now nice and rough. invest in a nice new dual flush toilet and only ever use the half flush?
i'm a bit confused tbh, you dont want to waste water by flushing each time, but you are happy to use more toilet paper to prevent splashing ?

save all your household waste water from baths/washing up etc and use that to flush the loo inbetween normal flushes?
if you havent made any huge differences to your diet, but are suddenly feeling more lethargic and have the runs, you should see a doctor tbh! if it is a stomach bug , you are not doing yourself any favours by not flushing. if you dont want to use chemical cleaners , make your own antibacterial spray with 2 parts cheap vodka to 1 part water, with a few drops of tea tree oil, to use in the sink, around the toilet bowl etc. if you are worried about put oils down the toilet, make one for inside the bowl that is just vodka and water. and maybe try using a hand sanitizer as well as washing your hands for a bit, just untill any bugs are gone ( again vodka,water,aloe vera gel and a few drops of essential oil mixed together make a good natural alternative to shopbought ones)
hope your tummy and toilet seat are back to full working order soon
