Approximately 1 in 3 people suffer from bouts of insomnia. While many resort to sleep meds (which have been shown to lack long-term effectiveness) or have given up hope that better sleep is possible, a scientifically-proven treatment does exist. Cognitive behavioral therapy for insomnia, or CBTi, is considered the first-line, gold standard treatment for insomnia and typically leads to noticeable improvement within 4 weeks.
