I went cold turkey for a week when we forgot to take it on a trip. No problem. If you are only taking it once a day, very little stays (less than 1/2) past 8 hours. So, you taper off every day. Some need to take it 3 times a day for more serious conditions plus some take much stronger doses.

I cold turkeyed off Klonopin to gabapentin. I did not notice a problem with the benzo either.

Any withdrawal would likely be at the most just some uncomfortable twitches or such. It would be easy to break up pills so you could taper off. 600 to 300 to 1/2 of a 300 would be an easy taper off.
