I had gall bladder surgery, and to begin with was afraid to take it. I eventually became so paranoid that I would have pain from my surgery(even after I was better). I began to take it even if I didn't need it. It gave me semi-high a feeling, felt like superwoman, and would even use it for nerves. After taking it for about three weeks, the last two times I took it, I had major chest pain epsiodes that would then, a few seconds after, would make me break out in a sweat and become nauseated. My ears would ring and I would go numb. VERY SCARY!!! After the second spell, I thhew the rest in the garbage. This stuff is very addictive! Please take only if needed and as prescribed by your doctor.
