I don't know if the tinnitus was made worse, but during my withdrawal I was working on CBT and other strategies to reduce my reaction to it.
My only Clonazepam prescription was given to me in August 2017. It was for 1 mg, twice a day, with a total of 42 pills (three weeks' worth). However, I never took an entire pill. I only took half a pill or less, never more than once a day, and rarely, if ever, on two consecutive days. I continued this for five months, starting slowly. I did not really taper, since my doses were so small from the beginning and I had no idea how to properly do it.
To summarize, from August through the end of December 2017, I took small doses of Clonazepam—0.5 mg or less—a total of 32 times, with about half of those instances occurring in December. I kept track of all of this on a 2017 calendar. In December alone, I used no more than 7.5 mg in total. I never took it again after that month and disposed of the remaining pills by the end of December.
I do not think my experience is typical. Fifteen years earlier, I had taken small doses of Alprazolam a few times a week for five years, which was a much longer period. Even then, after a very minimal taper, I experienced virtually no withdrawal.
