Pramipexole
"Started using pramipexole when weaning from zolpidem at sleep clinic. Long term insomnia complicated by shift work/school/age/family history. Pramipexole at 0.125mg/qd worked for about 9 months. Less effective if taken with food. Now, after a year, about 3 X week, first dose insufficient, so I take a second and that works. No side effects in gastrointestinal or balance/reaction time."
