What can you do if you have any of these symptoms?
First, I would look at how much you are eating. Are you eating enough? If not, I would start there and make sure you are consistently getting in enough calories.
Second, I would look at your sleep. Make sure you are sleeping between 7-8 hours a night. Sleep is usually the one thing that most people neglect. So many of us convince ourselves that we can get by on only 5 hours of sleep and we "feel fine" the next day. Ever feel that 2pm crash? Usually you just reach for an extra cup of coffee to hold you over for the rest of the day. Instead, ditch the extra caffeine and just head to bed a little earlier!
Lastly, I would look at your exercise. Making sure that you are putting your body under a bit of physical stress during the day will be important to helping you become more tired when it is time for bed. I know, I know, you're just not tired when you lay down so you watch tv, play on your phone, or start to read. Unfortunately this usually isn't going to help make you any less tired. It will only keep you up longer, make you more tired throughout the next day making you want more coffee, and the cycle continues.
In general, if your hormones are off, these are three easy ways to help you get them back on track. Give these techniques time to work. Remember, if you spent years under-eating, under sleeping, and either working out too hard to too little, your hormones will not regulate in a month. Give it time to work. If you do not see improvements within a couple months to a year, it may be time to visit your doctor.
