Hi, Thanks for posting in HCM. I understand your concern. From your history, it appears that you became addicted to this syrup as it contains codeine.It is advisable to stop this syrup as soon as possible. Phensidyl has some effect in sexual dysfunction. However, your problem is more likely of psychological in nature. Stress could be of one reason. You can overcome this problem by doing the following. 1. Take medication like Tablet. Tadalafil 30 minutes before intercourse to increase blood supply to the penis and get good erection. 2. Kindly practice pause and squeeze technique, which over a period of time helps you to sustain erection for a longer duration. 3. Overcome fear or anxiety by practicing meditation to keep your mind calm. 4. Spend more time during foreplay and gain proper confidence before doing the act. 5. Include in your diet - almonds, banana, pineapple, saffron, cardamom, figs, honey and pumpkin. Once you overcome these with improved confidence, you should be able to gain good erection gradually and perform better. Gradually you can reduce taking medications or take only when it is absolutely necessary. You may consult psychiatrist for advise regarding discontinuing and stopping the syrup.
