Clomipramine: steady gradual improvement or still a bumpy ride?

My husband has severe loudness hyperacusis and severe reactive tinnitus, as well as severe distortion to digital audio. These symptoms for the past 1 year. After 3 weeks on clomi (started at 25mg, now up to 75mg), he is having a 5-10% improvement. However, there are still so many fluctuations from day to day and days where we question if there is any improvement at all.

If you improved on clomi , did you feel the course was a steady improvement as you increased the dose? Or was it still very fluctuating with bad days ?

Thank you in advance for your responses 🙏
