Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. Well, it may be related to thyroid, so it should be checked. Generally, insomnia may be difficult to treat, but there are some methods which can be used. Treatment options include behavior and lifestyle changes, medicines, and complementary medicines. You need to change your dietary habits and these include changing your sleep area or schedule, watching what and when you eat and drink, and being more active. It s also important to keep regular bedtimes and wake times-7 days a week-and to try to avoid taking naps during the day. Prescription sleep medicines may also help and include Diazepam and similar medications. Melatonin is supplement which may be of help as well. In severe cases special testing is needed. Hope I have answered your query. Let me know if I can assist you further.
