Caber can have some nasty sides, but those seem pretty harsh for <1mg dosage. I've experienced weakness, lethargy, some nausea if dosed too high, and just generally feeling crappy. Nothing to the point you described though bro.

Could be a number of things. Depending how far apart you took those dosages, maybe too much too close together. Everyone's body is different. With that type of reaction, I probably wouldn't take it again. Maybe get bloods done and see where your levels are, you may not even need it. If you do decide to continue with it, might try a different brand and see if you get the same reaction. About all the advice I can give bro.
