Hi, it would depend on the individual patient. In patients on insulin who have a history of hypoglycemia (low blood sugar), we would need to be cautious with sleeping pills because they can get very drowsy and be unable to respond by waking to take food and drink if their sugar levels drop. Diabetes patients who have kidney impairment also need to have careful dosing of sleeping pills because they can get too drowsy when the sleeping pill isn’t cleared from the body  properly

The medical term for frequently waking up at night to urinate is nocturia. Broadly, this may be because of excessive urine production in general (poorly controlled diabetes mellitus, diabetes insipidus), excessive urine production only at night (congestive heart failure, obstructive sleep apnea, certain drugs), inability to empty the bladder (prostate enlargement) or inability to fully fill the bladder (bladder overactivity, bladder inflammation).

A consultation with a urology doctor will help diagnose the cause and set you on the path toward a more restful night. Untreated nocturia is associated with a poorer quality of life and can lead to depression, cognitive dysfunction, and increased risk for falls and fractures.

Hi @Edawaw if your ferritin is consistently low, you may have iron deficiency. If your haemoglobin level is below normal, then you should seriously consider iron replacement. 
First we have to make the diagnosis, you have to look at the iron saturation (it should be low ) and total iron binding capacity (it should be raised).
If you have these results, then consider increasing iron in your diet such as eat more red meat, take iron supplements.
Concurrently, you have to see your doctor and find out the cause of the low ferritin level. Is it blood loss in the gut, blood loss through menses or reduced dietary iron intake

Dear @cupcake-sprinkle , what you wrote sounded like you were experiencing the physical (headache, neck tension), psychological (angry, anxious, irritable, depressed) and cognitive (not think properly, not concentrate, cannot think) symptoms from stress and being on tablets & pills did not seem to make them go away. I can sense that dread as you wondered if you would ever get your old self back.

To begin with, speak to a professional who will spend time to explore what's causing the stress and provide you with a proper diagnosis before discussing the next step.

Identify the core causes.
If it's the hormone therapy, I would check my levels and consult a women's health specialist.
If there has been ongoing anxiety and stress, I would check in with a mental health counsellor or psychotherapist to learn relaxation, deep breathing, reframing mindset.
If the psychosomatic phenomenon requires temporary usage of medication, I will be cautious with diazepam or zolpidem use, and will prefer to discuss with the psychiatrist before using pregabalin and amitriptyline. SSRI or SNRI or Brintellix will be more suitable.

Do remember that we are ultimately still in charge of our bodies and how we want to look after ourselves. Take a moment, breathe and slow down. You can do this.
