First here's some background information on myself. I've had hearing loss and tinnitus since at least 1992, rating the tinnitus at 6-8/10 normally. I habituated early since I grew up in a rural waterfront area the summer nights were a literal symphony of bug, frogs ect that closely mimick tinnitus freq. Now my hearing loss has gotten worse so over the last month I've been wearing my hearing aids I bought 10 years ago. I've been paying a lot of attention to my hearing and the tinnitus is still pretty bad which lead me to this forum recently. On occasion I'll check to see what's new in the world of tinnitus relief. Since the hearing isn't the only thing that's failing me my doctor had given me a two week trial of Cialis to try out. By day four it was evident that my tinnitus had been drastically reduced, down to maybe a 2-3/10. As a experiment I stopped taking it and sure enough the tinnitus started increasing and by day 3 was back to its 6-8/10. Started the Cialis again and right back down it went. The unfortunate thing is my insurance company will not approve the Cialis for every day use only Viagra and then only 6 pills per month. It would be nice if I could get the Cialis approved for treating tinnitus since for me it makes a big difference. Has anyone else had a similar experience with Cialis?
