I suffered a major Baclofen withdrawal episode in 2012. My IT pump was malfunctioning, but without doing the tests to be sure it was the pump (dye test; removing contents, refilling, waiting a week, then removing contents again to measure; etc.), no one would remove my pump and implant another. It was six weeks of pure hell.
The auditory and visual hallucinations, insomnia, mania and depression, crawling skin, massive anxiety, and even psychosis and depersonalization. At first they tried to manage my withdrawal with pills by mouth, but that failed. I was admitted and started on IV Baclofen, which helped greatly, but then my pump delivered a massive bolus of drugs (morphine and Baclofen) and I almost died.
It's now nine months later, and though I have a new pump, I am scared to death that something will happen again. The pump manufacturer will not release the report as to what happened with the pump, which makes me wonder what *did* happen to it.
