I have been taking pregabalin high dose, between 600mg+ a day for a few weeks. Am I risk of becoming dependent, or does it take months to get it? I also take phenibut quite regularly and prescribed diazepam. I am scared to stop, as I have came off phenibut before and been ill for 10 days, the diazepam does nothing to help, I had to take a zopiclone in the morning, which helped, but still felt on edge.
