I have taken the same dose for 35 years and never had to increase my dosage. I guess I am one of the lucky ones.
It is just part of meds to keep my depression and anxiety in check.
Taking it to get high would never cross my mind.
I did all sorts of activities like skiing and hiking with my 42 year old son when I was younger. Even some fourteeners but these days I just walk outside or use an elyptical machine at my gym.
At 73 I don’t have any balance or memory issues.
Good luck to all.
