My youngest son got addicted to kratom about 5 years ago. He was taking several grams a day (I believe). He had 3 seizures before we found out what was causing his seizures(ER docs confirmed he had no drugs in his system thru blood tests). He took it to increase his ability to train in MMA fighting and it spiraled out of control. It took him a good month before he felt normal again after quitting cold turkey. He had all the symptoms of addiction withdrawal and had to take a week off work to start his cold turkey adventure. It sounds like you are not abusing it and it is helping you to cut down on Vicodin which is great. I just wanted to chime in to let people know that like everything else, kratom should be used in moderation.
