Can diazepam 2mg cause withdrawals when stopped?

I have been taking diazepam for 20 years, I've never had any problems with getting off of it. First off, a 2 mg dose is a very low dose. Anyway what I have been doing I is a take the 5 mg diazepam tablets 3 times a day for maybe as long as 10 days. Then I stop taking the diazepam for 2 or 3 days. Then I start taking it again. The 2 or 3 day rest from diazepam stops the possibility of my getting addicted to it. My doctor fro long ago suggested this method and it works very well, I take this drug as a muscle relaxer, Right now I am off if it. Bur if need be I can start taking it again and stop taking it, if necessary, without any problems. Been doing this for the last 20 years.

Yes, but your doctor seems careful to only prescribe it in the meantime for 4 weeks.

I take 5 to 10 mg per day but average far less over months. My experience at worse has been vivid dreams upon abrupt and sudden cessation. I believe it fairly benign. I hope this makes you feel better?
Good luck with your anxiety disorder. :)
