Hi Dr. Purushottam welcomes you to HCM virtual clinic! Thanks for consulting at my virtual clinic. I have carefully gone through your case, and I think I have understood your concern. I will try to address your medical concerns and would suggest you the best of the available treatment options. Let me answer your last query first. If you are regularly on Oral contraceptive pills , please do not worry about pregnancy. Secondly, sex activity will not lead to any of the symptoms that you are narrating. But at the same time 2 pills of 5HTP taken an hour before will definitely lead to dizziness like state. You can very well reduce the dose to 1 tablet after consulting with the concerned therapist. Also I will suggest you to indulge in healthy diet regimen containing good amount of first class proteins and regular exercise regimen, this also helps to generate effects like 5HTp in the body. I hope my answer helps you. Thanks.
