I throw up for about 2 days and had a lot of pain an cold sweats at night. The center uses Ibogaine to withdraw you off opiates. The Ibogaine did not ease my withdrawals, it may have distracted me away from the withdrawals for about a day but then it came back just as bad minus the vomiting. After 48 hours and of taking Ibogaine I gave up and relapsed to feel normal again.
