I have terrible tension headaches after taking everything from everything over the counter even the pm ones so my mom gave me a couple of her ultracets to take. This stuff makes me feel VERY weird. Very disoriented, can't hardly function (at work) I know I am here but it feels like my mind is off wondering some where, very dry mouthed, very tired, was up all night last night. The list goes on and on however my headache is GONE!! That is what I was looking for!!!
