Hi, I am new to this group. On 9/23, I went to urgent care because I felt imbalance while walking on 9/22. And then I was told my EKG showed some abnormality. I've been panicking because I had a heart surgery 10 years agao when I was 30. I waited for my doctor to email back and those nights, I had a hard time sleeping. I thought it was on temporarily, but it's been 12 days and I can't believe I still can't sleep, not even a second nor did I able to nap. I feel more energetic than ever. As day goes by, I feel totally stressed that I really want to cry at night. I now know how people get anxiety and lead to depression. On the 4th night when I couldn't sleep, my doctor prescribed me doxepin and it worked well. It gave me 6 hours of sleep and 2 hours of nap. The next day, I was yawning and I was confidence that I could sleep, but I was wrong. I then tried doxepin for 4 more days and didn't work at all. I am completely frustrated. I went to Chinese herbist for herbal medicine and at the same time my doctor asked me to try Ambien 5mg. I went with herbal medicine tonight. I've been yawning and thought it was a good sign. The whole night was tossing and now up looking for a forum. I was wondering if anyone has tried Ambien 5mg. How did it work for you? I always want to heal naturally, but I need ot gain back some sleep time in order to stay healthy. Please share with me your experiences and what worked for you?
