I feel fine in the morning and all day but for the last two days I have been getting very dizzy at the end of the day, around 4
Hello, If this is only a symptom that has been happening for the past 2 days I would recommend you increase your fluid intake for the next several days using pure and fresh WATER.  I would cut out caffeine and caffeinated beverages.  Make sure you've been getting plenty of rest and I believe you should start feeling better.  You say you haven't changed your eating patterns but do you eat your meals on time or do you skip depending on the need at school or at work?  Otherwise, if your symptoms are not self-limited over the next day or 2 you may wish to schedule an appointment with your doctor for an examination and some laboratory analyses to check on things such as electrolyte disturbances, blood counts that may point to anemia or infection, etc. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
