So apparently the reason Britney is coming back to being her old self is because when dealing with mental problems and doctors prescribing medicines, it can sometimes take 2-5 years for the right drug combination to make the person not feel like a zombie, depressed, angry, etc. Every new drug combination is tested on a 3-6 month basis, which helps explain why during the I Am...The Femme Fatale shoot----FF Promos, it looked like Britney was a little bloated, and then the bloating stopped about 4 months afterwards etc. Finding the right combination is essential to a person feeling 100%.
I know this personally because when my mother had depression, they put her on different combos of drugs, and some days she would feel super depressed and robotic, and then a new combo would come and she would be literally void of any emotions, etc.
It explains it, and it certains helps show why Britney has been looking better and happier over these last several months

I am positive and optimistic about the comments that she has fully come back
