Holly York, 30 with her baby Leo. See SWNS story SWLIMIT; A new mum who suffered extreme psychosis after giving birth felt like she had taken a real-life Limitless pill - like Bradley Cooper in the hit film. Holly York, 30, was sectioned under the Mental Health Act after experiencing the effects of postpartum psychosis - which made her want to slit her own throat. The first-time mum barely slept in nine days after little Leo was born and felt like a superhuman who was constantly on cloud nine. She whizzed around the house at 100mph - changing nappies, feeding the baby and keeping the house perfect - while husband Adam, 31, watched on in amazement. But the mania had terrifying consequences. Personal trainer Holly was sleep-deprived and paranoid and suffered vivid hallucinations - including seeing her own dead body on the kitchen floor. Her symptoms mirrored those experienced by Bradley Coopers character Eddie Morra in the 2011 thriller Limitless, after he takes smart drug NZT-48.
