Never tried DHC nor do i know what its prescribed for or does, withdrawels from opiates are similar to heroin as opiates are derived from the poppy plant where heroin comes from so yea it can be really horrible.. The restless legs you get, i get from tramadol and its first sign of withdrawel/craving, not nice at all.
As for myself i dont crave it no, i really think due to the high levels of tramadol which is an opioid just like codeine is whats give me a tolerance to it and personally think it would take double the daily dose for me to become addicted but wanted bluelights opinion on this. I do however have an addiction to tramadol even though its just 2 50mg caps per day, its more of a habit now, i use to take 15 a day
