Next time you head to the store, pick of a bottle of NOS. It's an energy drink, in a blue bottle with an orange cap. It has Ginseng, Taurine, Caffeine, and L-Carnitine in it. It's carbonated, and while I am not a soda drinker, I can handle this. When I feel the first twinge of one of my headaches coming on, and it's always in the middle of the night, I get up and take a swallow, then take another sip and hold it under my tongue for about 10 seconds, then repeat that a few more times. Within 5 minutes, all symptoms have stopped, and I can go back to sleep. Before I found this, I would be up from anywhere of 15 minutes to 4 hours! You can not lay down with these headaches (Clusters), so I have to walk. They are also referred to as the "Suicide" headache, because of the intense pain behind the eye. People are known to bash their heads on the wall and counter tops to try to relieve the pain, or else re-direct it? That didn't sound like a good idea to me, so I got on a help forum for them, and while most use oxygen these days, (which did not help my Dad), one guy in there asked if I had ever tried Red Bull. I went out the next day and got some, but it did not work for me? I also bought a bottle of the NOS while I was there, and tried it the night after when the headaches struck again. Within 5 minutes, I was back in bed! What ever is different in it from the Red Bull, it works for me, and is nothing short of a miracle as far as I'm concerned!!
