I recently had some changes to a medication I stopped recently, I was taking a mini press for ptsd symptoms and also increased my anti depressant from 150 to 150+ 37.5. I stopped the mini press because my sleep has gotten worse. I sleep about 5 hours intermitently through the night. I also have sleep apnea but I do not use a cpap. My sense of smell which I havent had for many years has all of a sudden come back. Also my eyesight has improved. But I now get these intense headaches, Ive had one now since 3am yesterday. Do you think this is a medication issue or has there been some kind of physialogical change in my brain.
