Welcome to icliniq.com.
I will start with the pharmacological part. You can discuss with your treating doctor regarding increasing the dose of Clomipramine, not only will it help with sleep but also in decreasing the obsessions. You can also discuss regarding substituting it with Fluvoxamine if not given a trial yet. Now a few points regarding non-pharmacological methods that can help with OCD (obsessive-compulsive disorder) are as follows. Practice patterned breathing exercises like Sudarshan Kriya daily, practice steps of sleep hygiene like sleeping and waking up at a regular time, avoiding caffeinated drinks at least eight hours before sleep, avoid using tv, mobile, laptop, etc. half an hour before sleep, instead do relaxing activities like taking a hot shower, after going to bed, do 4-5-8 pattern breathing that is, inhale for four seconds through the nose, hold breath for five seconds and then exhale via mouth for eight seconds. Repeat 4 to 5 such breathing cycles; it will help you relax and sleep, BMI (body mass index) needs to be taken care. You can also take CBT (cognitive behavioral therapy) sessions with a psychotherapist. I know it is easier said than done but try to accept your obsession, but not the fear or anxiety associated with it. Logging down your obsessions sometimes helps relieve the associated anxiety. Thank you.
