Stopped cold turkey Sunday April 25th after 55 years continuous heavy smoking. First 2 weeks were a doddle no withdrawal symtoms. I now feel as if my whole world has crashed about my ears. Can no longer concentrate to carry out a conversation. Unable to sleep. Badly constipated. Short term memory completely gone. Filled with depression & anxiety. Strangest thing I have no desire ever to smoke again. I can only pray these horrible symptoms will ease & I can get some of my life back. To all of you out there suffering, please join with me in our determination to get this monkey off our backs. Daniel.
