I have been on Targinact for 2 weeks in conjunction with Gabapentin & Ropinirole - it's been transformational , with no more standing up swaying during the evening plus I am sleeping much better now. I would say 95% gone. I hope it's not temporary as that was my experience with Ropinirole years back.
Next step is to back off Ropinirole. (slowly)
I can't believe that I can actually sit & watch TV for 2 hours before bed. Downside is that I can't have a glass of wine as it's a no no to alcohol.
