question: Dear Dr.I am a healthy 25 year old male, 180cm, about 90kgs. Non-smoker. I have suffered from panic attacks in the past and was treated with anafranil and therapy for about 2 years. My dosage was high, 200mg a day. I weaned myself off the meds 3 months ago, everything went fine - I feel great. the only problem is that my libido, which died completely during the course of the treatment, has not returned. Even if I do get an erection, I am just not really interested. I am worried about the effects on my relationship, I am crazy about my girlfriend. How long should I wait for it to return before I should start to worry?  Thank you
