Taper off 5mgs

I was on 5mgs of Lexapro for a little over 6 months and my psychiatrist told me I could quit cold turkey, so I did 3 days ago. Today I felt like I had vertigo and dizziness so I took a 5mg tonight and think I am going to take one every other day for a few weeks to lessen the side effects. Is the tapering or cold turkey better? With the taper, how long should I be taking every other day?
