I was just prescribed 0.5mg bid (2 x day) for anxiety. After I take it in about a half hour I start to feel the effects. I feel like myself, the way I should feel everyday. I feel like a better person, husband, and father. But after only 1-1.5 to 2 hrs tops I lose that feeling and am immediately overcome with anxiety, and the anxiety seems to be worse than before I started taking the medication. I even thought that maybe my dose was too low because of the lack of quality duration so I tried a double dose the for my second dose. All this did was make me tired and a little irritable and even maybe a little depressed. Do I need to give the Klonopin time to build up in my system a bit because of the longer half-life or am I just one of the few this drug won't work for.
