Insomnia...

Hi everyone! Maybe one of you can help me here... Lately, i have been getting terrible bouts of insomnia at night. My baby is 9 weeks old and usually sleeps for several 2-3 hour stretches at night, waking up in between to eat. However, the poor babe is getting over a virus and while she was sick was waking up every hour. She is starting to feel better now and sleep a little more again but I can't seem to! I just lay there awake and exhausted all night and it's terrible! Anyone else been through this? Any words of advice?
