I used to drink nothing but Mountain Dew. Nothing. It got to the point where every morning I’d wake up with a splitting headache and it wouldn’t go away until I had a can of soda. Even after waking up and drinking a soda, I’d have headaches pretty regularly. I never thought it was weird: I thought it was normal for people to go through buckets of headache medicine like I did.
When I lost my job and had no money, I switched to water and Kool-Aid, exclusively. About a week after I gave up my precious Mountain Dew, I hit bottom and experienced serious withdrawal symptoms. There was a two day period where I had a constant, agonizing headache (I wouldn’t say it was the most painful headache I ever had, but it was up there, plus it lasted all day) that made it impossible to do pretty much anything but sit around throbbing.
After the headache subsided, I felt way better than before it’d set in at all. I’m back to drinking soda but I stay away from anything that has caffeine in it (Crush, Sprite and Squirt are my drinks of choice) and I haven’t had headaches at all.
I’m not sure if I was just an extreme case, but to anyone out there who has headaches on even a semi-regular basis and thinks it’s normal, I seriously recommend giving up caffeinated drinks. You’ll feel loads better once you do.
