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.
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?
