Try relaxation therapy with biofeedback.
Tried relaxation and positive feedback and that did not work either.
A Harvard study in 2004 demonstrated medications are not the best treatment for insomnia, but rather Cognitive Behavioral Therapy for Insomnia (CBTi) is better. CBTi is safe in the long term, is less expensive, has no side effects, and treats insomnia at the root cause instead of just trying to "knock someone out" like medications do. If you go see a sleep doctor in person, CBTi is what they will recommend. Alternatively, online programs have been found to be equally effective and less expensive.
Rest well!
Sedatives are helpful to tide over temporary insomnia. Please don't use them long term. Either way to most of the sedatives (sleeping tablets), people develop tolerance, that is they stop working very effectively with time. So, try to develop good sleep hygiene. Sleep and get up at the same time every day, avoid smoking, alcoholic and caffeinated beverages and exercise regularly. Please consult your primary care physician if problem persists to rule out a sleep disorder.
Hope this helped and do keep us posted.
