Thank you so much for your response, much appreciated it. I was reading about Sustiva and its long term use side effects. One of many reason I would try the new drug biktarvy.

To be perfectly honest, the potential downfalls of the Sustiva in Atripla may be a factor you want to consider. I know a number of people whose brains have been affected from long term use of Sustiva (even in Atripla), which has caused them many problems, including the inability to hold down a steady job due to mental limitations. This may make it worth switching before this happens.
