About two months. Was put on it because of my T, but truthfully I should have been on meds much earlier for different mood reasons. My T is multi-frequency range from mid to ultra high. I firmly believe positivity is the key to improvement, along with supervision from a audiologist/hearing therapist specialising in tinnitus, along with phyciatric supervision for medication.how long have you been on zoloft? did you start because your T put you in a bad place? or is your T not loud and your taking it for something else
