Is it normal to have non stop headaches

There are so many potential reasons for this, both serious and non-serious. The only way you'll know what the real reason is, though, is to see a doctor.

Yes it is normal, for people who don't drink enough water or spend too much time in front of the computer or TV. If you watch TV or are on the computer a lot, try to keep your eyes away. Also, you could get your eyes checked, because sometimes it means you need glasses. You should also try to stay indoors, breathe fresh air (perhaps have plants in your house, but I mostly meant to stay away from the gas station and other fumes), and drink a LOT of water. I hope you try all these things. If it doesn't work, visit a doctor, because they know better than I do. I've had the problem and it was sort of an "all of the above" thing for me. So try it out, see what happens. Hope your head feels better; headaches can be a beast!
