Also Cognitive Behavioral Therapy for insomnia is excellent as well. It helps treat insomnia for biomedical and mental health conditions. I plan to certified in becoming a CBT for insomnia and other disorders.

Yes.factors associated with disrupted sleep In people with diabetes include nocturia( toilet visits),overnight hypos-,peripheral neuropathy,restless leg syndrome and sleep disordered breathing.Metformin can result in sleep disturbance.
Recent research suggests taking midday naps reduces the risk of poor glucose control if you sleep less than 5 hrs undisturbed.
Melatonin and Antihistamines( Benadryl) are the most popular way of treating I somnia according to diabetes blogs( they are not so strong as to prevent you waking from low bs or in an emergency)

Not sure whether it's diabetes related but it can be due to something else like a loss or chronic pain. I experienced it when my husband passed on, it was very tiring not getting sufficient sleep. I managed to slowly come to terms with my loss and have manged to sleep well again, however I must say I go early to bed and wake at 4.30 I meditate and practice yoga which contributed a great deal. Hope this helps sending positive thoughts and light, tc. 🙏

Thanks for answering my question! Much appreciated
