Hello Divina,
I very strongly feel that the low energy levels of ur friend r due to his sleep apnoeas. The people suffering from this problem very commonly have day time drowsiness and low energy levels. Didn't the study people tell him the cause and management of that??
U have not mentioned enough to deduce the miasm of this person in totality. But childhood Asthma is primarily sycotic. And his tendency to stop breathing at night is also very much sycotic, but can be Psoric too depending upon the cause.
It seems very likely that this man needs a constitutional which covers his symptoms too. And knowing the miasm will definately help in that.
U need to elaborate as to what u mean by one miasm feeding into another?
