dear, alt levels has got no relation with sleep disturbances per se. sleep disturbance here is a mojor concern which at may predispose to cardiac complications and then it s a vicious circle. An underlying depression could also set in if it persist. Here our scope of intervention lies in setting up a healthy lifestyle and maintaing proper sleep hygiene. my advice to you is to avoid caffeine and stimulants after 6 pm. avoid large meals in dinner. use bed only to sleep, do not lie ideal without sleeping. If you don t fall asleep within 5-10 mins of getting in bed, get up and do some thing else. Have moderate physical exercise in morning for half an hour. If symptoms persist despite of these modifications then a course of anti depressant be useful I suggest your doctor to add tab fluoxetine 20 mg in morning tab alprazolam 2 mg half hour before getting in bed thanks
