Do not use too much, I have used it and it forces you to rest. We tried it on my sister with a humongus brain tumor, it was too late, but she only suffered for about 2 weeks. God blessed my family with what we prayed for, a very quick death. My sister worked the day she went to the hospital, because we thought she had a mini stroke because she couldn't remember nouns. The nurses at the hospital were shocked at how she was totally normal functioning except for not remembering some nouns. A new nurse would come in with a bed pan and tell my sister time to go potty, so my sister jumped up and went into the bathroom. She didn't fit the chart, she had a 4x6 tumor and should not have been functioning that well at all.
