I've taken too much kratom and felt like my eyes were rapidly twitching side to side. Made my vision blurry and gives me motion sickness. I don't know if that's what you mean by "wobbles".
I take kratom every day. It's good as an opiate maintenance med, keeps me from getting back on opiates, and it helped me when I was in a bad depression. I just wish it had a longer half-life, it's inconvenient to take when I'm not at home and I'm looking for a job right now. I'm tapering off just so I don't have to worry about that hassle.
I'm kicking myself for not getting a Suboxone script when you could still get them via telemedicine in my state. I asked my psych about it recently, but they won't give me one unless I'm in active addiction and get a positive drug screen to prove it. Pretty dumb that the system requires me to have a relapse to get the meds to prevent a relapse.
