Call the Midwife teases a dangerous development for Trixie
"It's the insomnia that's tearing me to shreds," she says. "I keep waking up and then when I do eventually drift off, I suddenly feel as if I'm falling or being pushed from somewhere very high, and then I'm lying awake again."
When Dr Turner suggests signing her off for a while, Trixie tells him that she'd much rather continuing working. But without a good night's sleep, she is unable to do her job to the best of her abilities, which isn't only a risk to her own safety, but that of her patients, as we saw in a previous episode when she was distracted by Matthew while tending to a woman in labour – with devastating consequences.
As a solution, Dr Turner prescribes Trixie some sleeping pills, but they are only to be taken "in the short term".

Now for any other character in Call the Midwife, taking some sleeping tablets wouldn't be huge cause for concern, but given that Trixie is a recovering alcoholic, the stakes are significantly higher, as the character reenters uncertain territory.
Her dependency on drinking was initially presented as a facet of Trixie's party-going persona in the show's earlier seasons, but over time it became apparent that she was using alcohol as a crutch when life's great stresses overwhelmed her – and her current predicament is certainly one of the greatest challenges she's faced.
