The real preventive solution is to get SAS installed. At its simplest (without autopilot) it acts basically as a fancy trim system, though based on aircraft attitude rather than control position. But to oversimplify, it keeps the cyclic at basically one position and you can counteract it but you'll feel resistance. Aside from increasing flying comfort, it significantly increases safety as it will not do a forward pushover like a pilot might. I bought an R44 without it and then added the SAS and autopilot a couple of years later. It's a great system.
