Insomnia

Have just started my taper from 200mg Pregabalin, 9 months on it. Reducing 25mg per month but may switch to a liquid taper when I reach 150mg. For the past 3 days have had horrid insomnia - unable to sleep at all. Have had to resort to Zopiclone which not happy about as just got over that habit. I don’t know what to do. Has anyone else had this problem and will withdrawal insomnia pass?
