So I have bipolar disorder, mixed and anxiety/panic disorder. I take Klonipin as needed for the anxiety. So last night I was so tense and anxious I took 1mg around 1145pm. Within the hour I was calm but by 830/9am I woke up shaking and experienced all the physical symptoms of panic. Shouldn't the Klonipin work longer than 8 plus hours. (Side note I did wake up in the middle of the night starving and ate like three handfuls of chips and a glass of milk. I don't know if that contributed and if so why). Thank you! This is the first time this has happened. I thought Klonipin was supposed to last 24 hours. Any feedback would be appreciated. I hate this feeling sooooo much. It makes me want to take another one as soon as I wake up but I don't want to do that and build up a tolerance so today I powered through it and now it's slowly starting to go away but it's taken abt 90 min to even feel relief.
