The urge just to go and nothing else kept me awake. I couldn't find an answer. Sorry your going through this. Not getting sleep compounds all or any other problems your having. It's terrible. I know. I went through the no sleep for a long time. And working eight hours a day with 3-4 hours off and on grinds on your state of mind after a time.
I hope you can find an answer. It sounds like it works fine otherwise. I found that mashed potatoes or cheese slows it down significantly. But if you try this use caution. It only took a little for me. Too much would cause a blockage. And you do not want that.
