Welcome Spillway and Byron1122. Really!
SE has a lot of similar symptoms and methods to releive them. We may learn a lot from our common affliction.
However, I want to be careful in treatming them identically. We've had a lot of discussion (on the NSF forum), especially related to neurotransmitters, and have found that on general terms, treatment on modifications of neurotransmitters either by direct administration or indirect influence, has had little positive influence for us.
It could well be however, that such may not be the case for SE.
There is a big difference between POIS and SE. In our case, one orgasm can knock us out for up to 2 wks and more, and it isn't necesarily related to prior excessive sex. There are those with POIS that have had POIS since their first days of puberty. Many who've had it within the first few years. Some of those even, who may have masturbated a great deal, but then who of most males in puberty hadn't masturbated to excess without having lifelong POIS and or SE?
We have measured neurotransmitters, vitamins, hormones, auto-immune components and have tried to boost whatever is low, or lower whatever is high, but to little avail. For us, low levels are symptoms not causes! Symptoms of a root cause. Without identifying the root cause we have lottle hope of resolving the problem.
Dr. Waldinger has given us a little hope because he has seemed to identiy one potential cause. It may not be the only one, but already and based on his reports, we have had some very decent results based on resolving the causal issues, rather than the sympomatic ones.
One of our menber, Lauracostis has also identified another potential causal area (I'll include the reference as soon as I can get to it), which relates to complex factors in the hormonal chain related to orgasm.
I'm sure that SE also relates to such other influences, but as the result, most likely, of a sort of systemic fatigue. Ours does not appear to ba a fatigue which can spring back with proper attention.
Anyways, let's see where we can help each other.
