You will not necessarily have increased s/e's with your start up...some don't, so hope for the best, but it is good that you can plan on going back to .5 if you need to.
It can be that you need to bump up to get to a therapeutic point where the Rx is actually doing something for you...so getting to the minimum dose is a good goal, IMO.
Wishing you continued improvement! Remember it's not often a linear line...but you are on the right path!
Stay encouraged., and keep us updated so we can cheer you on.
