Hi.
Sorry to hear you are struggling.

From my experiences, Ambien did only work for a short time. I tried some atypical antipsychotics at the cost of feeling tired the next day; Seroquel and Zyprexa really knocked me.
What seemed to work were older/more potent benzodiazepines. Within the benzos, there are still options such as Rohypnol (flunitrazepam) that are potent. They are, like barbiturates, not commonly prescribed.

Typical antipsychotics such as Haldol, Thorazine and so forth may cause extrapyramidal symptoms like what you have described.
