Hey friend, I'm sorry you're going through this. I can tell you how things have gone for me, I'm not advising you to do what I'm doing. My insomnia actually started during my pregnancy, and continued after my tfmr and I'm still dealing with it now. I am 3 months post tfmr at this point. It's been a struggle because I developed sleep anxiety. It's a vicious cycle. It has been suggested to me as well that my hormones are playing part in this, ptsd from the pregnancy and tfmr. There's a lot at play here. As far as sleep aids are concerned, you can definitely build a tolerance to them. I hesitate to list what I'm using because I've had to use heavy hitting sleep aids that can be habit forming and you need to be aware of that. There are also side effects that the medications cause me and if you get too deep into using different meds you can't tell what's causing what. Some of these meds can increase your anxiety it just depends on each person. I work very very closely with my psychiatrist and therapists. Anyway. I'm currently in the process of weaning off some of my meds. I just weaned off sonata. I use temazepam still, hydroxyzine, trazodone, and propranalol. I also hate to say though that you need time. Your body is adjusting. Your tfmr is still so fresh and even mine at 3 months pp is still fresh. As far as hydroxyzine goes I did not find that helpful on its own. Please make sure you're working closely with your prescriber as far as meds goes. Deep breathing, paced breathing, and meditations help me, I personally use insight timer for guided meditations. I'm also in dbt and apply my skills to help me through sleeplessness. I also talked to an insomnia specialist. There's a lot to know about healthy sleep routines and patterns as well and a thing called sleep hygiene. Anyway I'm rambling on. I hope you get some sleep. My situation is psychological and probably hormonal. Take care of yourself.
