Tired and shaky. But dont feel ill.

I would advise you to do a complete blood count(CBC) to note your hemoglobin levels and other parameters for any abnormalities. You could follow the following lifestyle changes which could help with your fatigue: - Drink lots of water and stay well hydrated at all times of the day(Aim to drink 2.5-3 liters of water everyday) - Be careful with caffeine aim to drink caffeinated drinks such as coffee, tea, cola just 1 or 2 times a day, above 6 such drinks would make you irritable, anxious and will negatively affect your performance - Don't skip meals, Eat healthy, clean and nutritious diet, Don't crash diet - Eat iron rich food - Adults need upto 8 hours per night - Destress yourself with methods such as yoga/meditation. - Exercise regularly If the symptoms are persistent and worsen visit the nearest ER for further evaluation.
