I'm acutely porn addicted ...how can solve this porn addiction?

Cold turkey: You need to stop visiting porn sites immediately and completely. You have already made a good start by recognizing that your behavior is a problem. Try to find something else you enjoy that keeps you active, e.g., going hiking, playing an instrument, gardening, being at the beach, playing chess etc. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form.

Seek real love: All men seek out and enjoy images that are exciting to our romantic sides. This becomes a problem when, and only when, it starts interfering with your getting to appointments or doing other things that are important in life. Porn is a dead end -- this world of perfect bodies is a fantasy & will disappoint. Look for a real relationship -- even a warm friendship -- and perhaps you'll find true love.
