I was prescribed Tramadol hydrochloride 150mg yesterday for lower back and leg pain. I had dreams when I did sleep but woke many times during the night. When I got up today I felt spaced out and not with and quite weird. However I went to work in Retail. I was talking faster than normal and my thinking was affected. At lunchtime I ate a banana and had a small protein drink to try to make the strange feelings go away. Mid afternoon I vomited quite heavily twice but did feel a bit better after. I was really pale and my voice was scratchy. I came home and slept for 3 hours. Can't face food yet but feel improved. I would like to know why I felt this way and certainly won't be taking another tablet again. Tk u
