Night symptoms

I have been detoxifying for more than a year now. Some of my symptoms have eased, such as gum bleeding, red spots in my face and chest, chest pain, brain fog also decreased.

On the other hand I have terrible nights. At the moment I fall asleep my symptoms increase and I wake up again and again with chest pain, breathing difficulties and pressure in my head.

It also makes difference if I lay on my back, on my side or on my stomach. It is only bearable laying on my back. Last night I laid on my stomach and I woke up feeling so bad that I thought I would die. I almost lost consciousness and sweated like I would have been Fred Aster in the rain.

Has anybody similar symptoms, has anybody an idea about the cause or a solution to that problem?
