Hey! I'm going to be completely honest here. I just checked out the ingredients in 'Withdrawal Ease'. I've taken all of them - though not synergistically. They're all good for different reasons but in my experience, unless you're on your first habit and it is mild - these remedies will not be of much use for sleep, etc. until you're past the acute phase. I've found that the longer time I have between me and my DOC, the more I can feel Passionflower, etc. I found 'Natural Calm' helped a little during and right after the acute phase. May I ask what you're detoxing from, your dose and how long you did it?
As a Certified Alcohol and Drug Counselor, I'm not a fan. It is mainly an herbal substance which tells me its probably not going to help your symptoms much more than Motrin, Immodium, and keeping yourself hydrated throughout the withdrawal process.
