Does anyone know if we go through a withdrawal when we are finally on top of things and better? I mean, recently I feel I have finally reached a calm that I haven't reached in a long time and now I am feeling so tired, I have palpitations, shortness of breath, fullness in the head . .. I was wondering if once our body reaches a calm state after being so revved up so for so long, if we kind of have withdrawal symptoms as our bodies try and get back to normal -- is this possible?
