In Italy the doctor put me on magnesium drinks that you take 3 times a day and I did notice an improvement but could have just been coincidence as by this point i'd been having attacks everyday for over a month and was beginning to calm down a little. But my doctor in the UK when I mentioned this said she didn't really believe in magnesium supplements as helping with panic attacks, and in the UK I was taking magnesium in pill form which didn't seem to help strangely enough so I'm not sure what to think
