I wish I had read all these posts before I took this awful stuff. I have experienced almost everything listed here except nose bleeds. I had a severe sinus infection and ear infection. Taking antibiotics, too. The first pill I took made me very sleepy, but then went in reverse. I slept for about 2 hours and woke up at 1 am unable to go back to sleep even though I was so tired. I felt like I was on speed. I managed to go to work, I am a hairstylist, but felt nervous all day cutting hair and constantly had to go to the bathroom. I decided this was not for me and I went back to my afrin nose spray to relieve the congestion.
