Hey Baz,
I know that your problem causes you lots of distress and if I could give you some solid advice I definitely would but unfortunately, I didn’t do anything special, I don’t think. Sorry to not have an answer for you. I’ll tell you everything that I have been doing that I think might have been helpful.
I take Vitamin E, Vitamin D, Cod liver oil and a Centrum Chewable multivitamin. Recently, I’ve been taking a 500mg Cartinine tablet in the morning - I started taking this after my ED issues had resolved.
I drink pomegranate juice daily, that’s all I do specifically for Nitric Oxide.
I eat some spinach and rocket every day as part of my normal diet, I understand this is also beneficial for Nitric Oxide production but I don’t eat it for that reason.
I don’t eat anything that (to my knowledge) inhibits 5AR. This means lots of mundane things like tomatoes (though I still have ketchup on chips), soy, mushrooms, nuts, blueberries, liquorice root, coconut, that were regularly part of my diet are gone. If you’re not already doing that and would like to try it, a good start with this would be to look at hairloss websites that suggest 5AR inhibiting foods and just do the opposite. There are lots of them out there.
I try and keep my stress levels as low as possible at the moment. When I had ed issues I made a decision to not labour the point if it just wasn’t happening to try and stop myself from having bad, reinforcing experiences. Even though I haven’t had a problem getting an erection in a while, I still worry about it. If I had had repeated incidences of not managing it and then continuing to try, I think my worries would be reinforced and could have created a vicious circle where the stress and worry could have contributed to stopping me from achieving erection.
Though my sleep is crap, I go to bed early to maximize my chances of having enough time to get back to sleep if I wake up. This might mean 12 hours of my day is spent in bed at the moment. Sometimes getting less than half of that as sleep.
As I said, I’m sorry I don’t have a magic bullet and I don’t know the mechanism of your problems but it’s obvious you’re very distressed by this. It might be worth trying to decrease your stress levels, improve your diet (if it’s not wonderful already) and trying your best to not obsess about it.
