Dear HCM user Its common to have sleep difficulty during febrile illnesses like Typhoid. It maybe due to fatigue, malaise or weakness. It should resolve with your illness as your general health will improve. If it persists beyond that then only you need to be concerned especially if you have mood changes or loss of interest in surrounding along with. Presently you need not worry. Take rest. It will be better if you avoid outside food and juices as it maybe contaminated and instead have whole fruits at home after washing. Take things that are easy to digest like curd, khichdi etc. Hope you get well soon.
