You are welcome!
Having hangover-like symptoms of being drowsy, having a headache, being sluggish, and being irritable after waking up when Clonazepam is taken before sleep, is commmon side effect of this medicine.
This is likely the result of the medication's long half-life (being in the body, before metabolized and eliminated), which continues to affect the user after waking up, as well as its disruption of the REM cycle.
I have a suggestion for you to ask your doctor for thyroid gland hormones test.
It is a simple blood test, and it can be helpful.
Sleeping difficulties and appetite problems are characteristic for bipolar disorder, but, can be, also, due to problems with thyroid gland.
There is a connection between bipolar disorder and thyroid hormone status.
Sometimes, threating thyroid gland disorders can lead to resolving bipolar symptoms.
You said that you are cycling very quickly, and that you feel depressed and at the same time irritated, which can mean that you are experiencing mixed episode of bipolar disorder (having symptoms of depression and mania-irritated at the same time, and this pattern of bipolar symptoms is more usual for your age)
So, I'll share with you a clinical fact that thyroid problems are more common in the complex forms of bipolar disorder (mixed states and rapid cycling) than in classic bipolar manic patient.
Waiting for your post!
Best wishes!
