Yes insomnia is a huge Bartonella symptom in my experience, I went from sleeping easily at least 8 hours a night daily to getting no sleep for 2 weeks straight! I had to go on sleeping pills to actually fall asleep. I attribute this to a Bartonella infection. Getting on rifampin helped me tremendously with these symptoms.
In addition, sore throat, swollen lymph nodes, body inflammation, shin pain, anxiety, blood shot eyes sometimes.
