<s>[INST] Hello Doc,This is about my friend who is not aware of internet usage so i am looking some info for him. Below are the details he provided to me:-He is a 25 years old boy, suffering from Night Falls since last 5-6 years (twice or thrice in a week) and due to this, He has been captured by many other issues like:    Excess Night Falls (Already Mentioned)    Sperm and urine leakage    Premature ejaculation. (within few seconds)    Low immunity and digestion, weak body structure.    His Hair being premature white and having back pain often.  So please suggest medication to cure all of these issues and to regain his lost health and fitness. Thanks a lot. I am not sure but he feels Masturbation is the root cause for all these which he practiced couple of years ago (in age of 17-18th) for only few months on weekly basis. Then he left it after getting awareness that it is not good for health. [/INST] Hellenist fall is a natural phenomenon in this age group, so avoid using porn sites, reading books of excitement. Premature ejaculation and night fall both are associated with each other and this is due to psychological effect so consult a psychiatrist and get his opinion regarding these two problems. As far as concerned about lean and thin body structure, eat healthy diet and stop worrying (main cause of gray hairs). Eat high protein diet for immunity (increase). Consult a psychiatrist and get his opinion as in my opinion all problems related to premature ejaculation. Good luck. </s>
