I guess after all that what I want to know is this a withdrawal symptom because if it isn't then I need to get to the doctor because I don't think I can walk or stand without holding on to something.
I am a newb here and not the one to be answering, but since nobody else has yet... I would guess probably yes, but that doesn't mean you shouldn't get to the doctor or at least talk to your prescribing doctor about it, because that's pretty dangerous and you also want to rule out that something else is not going on. I know it made me feel dizzy, but nothing like that.
