7-OH NO
I've been a Kratom user for 10 years. Haven't done heroin or bought pills in that time. I have a local store than is selling sublingual strips for pretty cheap comparatively. So I decided to try it for the first time. First impression was it felt a little to reminiscent to my past endeavors. Past that, whatever, I'm not going back to where I used to be so I'm not worried there, but in the course of 4 doses over 2 days and my final dose at 8:30PM I woke up at 4AM with a decent amount of cold sweat and that weird tired/can't sleep feeling. Halfway to restless leg. I was pretty blown away. I don't go into W/D from Kratom and I space my very large doses out so that from 8PM until 4-4:30PM next day I don't take any at all.
For anyone thinking about trying it that has been addicted to hard opiates and use Kratom as a substitute, be aware that it absolutely will give you that feeling again, and will make you want to take more to stave off withdrawls almost instantly. This is my own experience of course, and doesnt have to be yours, but I've never gotten dependent that fast from anything I've ever done. I believe this is probably because I've previously had a long-term addiction to pharmaceuticals and H. And I'm probably more prone to dependency than other individuals without that experience.
Edit: people who have switched to 7-OH, have you guys gone through withdrawls from Kratom while switching over? I still took some Kratom during this time, but not my normal dose.
