Brief Answer:
you can try tadalafil,take tetrafol plus also

Detailed Answer:
Hello,

Thanks for follow up.

Occasional moring erection and some improvement with viagra suggest that there is no much physical damage.
5- PDE inhibitor group of medicines like sildenafil or tadalafil are used for erectile dysfunction(ED). One of them should be used 2 hours prior to sex. They cause headache, stuffy nose nausea and gastric discomfort like common side effects. Proper physical check-up of cardiac system should be done by a doctor before starting the same. These are prescription medicines and you need to consult doctor/psychiatrist/sexologist for the prescription.
Tadalafil is preferred in patients with blood pressure and it causes less side effects than sildenafil(viagra).

You can use medicine cum vitamin supplement containing pyridoxal-5-phosphate, mecobalamin and l-methylfolate (trade name tetrafol plus)is very helpful in my patients. It has shown improvement in 50-60% patients of mine with ED. You may get this medicine over the counter as it is vitamin product.

Consulting psychiatrist/sexologist will surely help you.

Feel free to discuss further.
