I have anxiety attacks which are worse at night. I can t sleep more than an hour or two at a time, and I feel impending doom , especially if I lay down. It seems somewhat better when I sit up. It also feels like I can t have a complete bowel movement. I always feel like I have to go to the bathroom, but when I get there it doesn t happen, or only partially and it feels like it s not empty. I do take hydrocodone. My doctor gave me hydroxyzine to help me sleep but I am a fraud to take it, the side effects sound really bad and I am 69 years old. What can be causing these problems?
