Question 1

Should I treat the insomnia or the anxiety first?

Accepted Answer

The relationship is bidirectional: insomnia predicts future anxiety onset, and anxiety predicts future insomnia. GAD has the most severe overlap (51-68% with clinically significant insomnia; Belleville et al., 2010, PMID 20369395). Treating anxiety alone produces only modest sleep improvement — residual insomnia persists and is one of the strongest predictors of anxiety relapse. CBT-I is the evidence-based first-line for comorbid insomnia (not sleep hygiene), and internet-based CBT-I produces moderate anxiolytic effects (g≈0.36; Ye et al., 2015, PMID 26581107). The pragmatic recommendation: treat both concurrently rather than waiting for anxiety treatment to fix the sleep. Trazodone 25-100mg is the preferred pharmacological adjunct when CBT-I is unavailable.

Question 2

How does the bidirectional anxiety-insomnia cycle work?

Accepted Answer

The relationship is bidirectional: insomnia predicts future anxiety onset, and anxiety predicts future insomnia. GAD has the most severe overlap (51-68% with clinically significant insomnia; Belleville et al., 2010, PMID 20369395).

Question 3

Can CBT-I be combined with anxiety treatment effectively?

Accepted Answer

The relationship is bidirectional: insomnia predicts future anxiety onset, and anxiety predicts future insomnia. GAD has the most severe overlap (51-68% with clinically significant insomnia; Belleville et al., 2010, PMID 20369395).

Question 4

Which medications address both anxiety and insomnia?

Question 5

How long does it take for sleep to normalize after starting an SSRI?

Accepted Answer
