How long do you stay on 5mg?

Hi all. I've currently met my deductible and attempting to get in a 90 day supply while it's still covered. I have spent a month on 2.5 and a month 5, losing 10lbs each month. My doctor gave me two options for a 90 day supply and I was curious what yalls experience have been staying on 5 for awhile. Was it for just a month? Longer? Was going to 7.5 way better? Here is what my Dr offered:

  1. A 90-day 5 with the understanding that there is a high likelihood that you may experience a plateau towards the end of that 90 days, or
  2. A 90-day 7.5 with the understanding that this could be denied by insurance (due to them seeing it as a 'titration' dose leading to 10mg) or you could have a plateau towards the end of 90 days.

Thanks for any advice!
