I took low dose modafinil (33 - 50 mg) for 3 months about 5 days a week and now I've noticed increased tinnitus (ringing in the ears). It's only slight of course and more noticeable in a quiet room. I think everyone normally can hear a slight ringing in their ears in a quiet room. But since the modafinil I've noticed it's definitely louder. Also whenever I take modafinil now (which is about once every 2 weeks) I notice changes in my hearing. Things seem louder somehow and my ears feel slightly blocked but at the same time more sensitive to loud noises. This wears off after a day but the tinnitus remains. Has anyone else experienced changes in their hearing?
