... first night but last night I forgot to cut the pill in half so took 50mg. I realized it about 5 minutes later but too late! :( today I have a raging headache mostly in the back of my head..is it probably from going up too quickly? I'm going to go back down to 25mg tonight but am kind of afraid to ever take 50mg again as this headache is excruciating. Thanks for any answers and support
