The magnesium chloride (the form you should be taking)has done its job ,but the mind works in habits. I think maybe you,ve felt like shit a long time so even though you have fixed the chemical side , the habit is still there.
Exercise is the answer for reasons you can research yourself , in particular kettle bell two handed swings.
As well as look up Dr budwig (flax-seed oil and yogurt)
Also Miracle-Mineral-Supplement chlorine dioxide (the shit works)
goodluck
