Magnesium for Anxiety

Following a period of immense stress I have been struggling with severe anxiety. After one day of taking magnesium citrate (CALM Natures Vitality) I felt like a brand new person and day 2 was even better. Days 3-5 have been gradually worse until day 6 now I had a panic attack again. I have been reading that it’s normal to have a good day or two initially then relapse into symptoms and then gradually improve over weeks. One positive thing is that all my OCD thoughts are GONE.
