Last weekend I had this problem I've encountered many times before. It happens to all of us on occasion. Suffice to say, it took place in our bathroom. I was in the bathroom squeezing and squeezing so hard I was turning blue in my face and yet could not get anything out. You know how exasperating and frustrating that could be. No matter how hard I tried, the result was nothing.
My wife knocked on the bathroom door and yelled that I'd been in there over a half hour. "Is there a problem? Are you alright?", she asked. I told her I'd been squeezing and squeezing and couldn't get even a drop out. She told me to try using a bottle of citrate of magnesia or some milk of magnesia in the cabinet under the sink. I found this big bottle of milk of magnesia and pressed it really hard on the bottom of the tube of toothpaste. EUREKA !! It flowed right out of the tube.
