Bobs34,Read this two articles;
I summarize for you : cause of Nocturnal Penile Tumescence (scientific name of morning wood) is believed to be REM activity (dreams); deprivation of this phase, or disturbs of it, cause lossen morning wood. I think you know also that anti-anxiety drugs, so well that althered psychologic life, cause lessen of REM phase.
So, as said, morning woods are in no way a proof of sexual disfunction or nerve damage.Nocturnal penile tumescence - Everything2.com
Hope it help.
I agree with this Bob, So the issue is to try to restore REM sleep.
About what Latency said, Their are several substances that can repair nerve damage but how be it it is very slow because nerves heal up slow.
Biotin, I’m currently taking this for nueropathy, Neurontin made me fat sad and psychotic.
Ginkgo Biloba has a chemical called NGF Nerve Growth Factor, The amount of ginkgo you have to take to stimulate nerve growth, this is what I am un sure of. I take 240mg standarized daily.
B12 good for blood vessel health and nerve damage.
Magnesium for nerve conduction 300-800mg per day, This is what I take
Calcium 1000mg per day.
I have managed to get the nerve damage under control, However my toes still get numb and fall asleep. This nueropathy use to go up half my legs and the tips of my fingers and the end of my dick.
Speak softly carry a big dick, I'm mean stick!
