It is generally not recommended to consume chamomile tea during pregnancy due to potential risks of uterine contractions and other complications. It is advisable to opt for safer alternatives such as citrus peel or orange peel tea, lime blossom tea, ginger tea, lemon balm tea, or rosehip tea. If you continue to experience difficulty sleeping, you may consider using antihistamines like Chlor-Tripolon or Benadryl. In some cases, a doctor may prescribe a short-term sedative or a long-term sedative antidepressant, depending on the cause of your insomnia. It is important to address any psychological components such as stress or anxiety that may be contributing to your sleep issues. If your insomnia persists, it may be necessary to seek medical advice for further evaluation and treatment.
