Is there any change in the water level in the tank? You can tell by looking in the tank. There's always a mark where the water usually tops out. If so, something has changed. Check the float.
Also, people sometimes place bricks or other objects in the tank to save water, but that can cause intermittent poor flushing. If you have anything in the tank that doesn't belong there, remove it.

We actually do not have anything in the tank, although I did think about it. My husband said it really doesn't do any good! Our other thought was to replace the toilet, but I guess I'm concerned "what if" that doesn't fix the problem. So we are taking working on one suggestion at a time, until we fix the problem.
Thank you for your replies.
