Iâm pregnant and have had a blood test for chickenpox. The blood test can show that you: 1  Are immune (have already had varicella disease or varicella vaccine) and have no sign of recent infection. You have nothing further to be concerned about.  Are not immune and have not yet been infected.
Causes of acute insomnia can include: 1  Significant life stress (job loss or change, death of a loved one, divorce, moving) 2  Illness. 3  Emotional or physical discomfort.  Environmental factors like noise, light, or extreme temperatures (hot or cold) that interfere with sleep.
All insomnia medicines can cause side effects like daytime sleepiness, dizziness, unsteadiness, and could actually worsen your insomnia. Sleep-walking, sleep-driving, sleep-eating, memory lapses, and hallucinations have also been reported. The risk of developing a dependency on the drugs is also a problem.
