Not using drops anymore due to side effects..good or bad idea ?

[HYPERHEAD]

I have stopped using any drops lately due to various side effects which I couldn't handle, like headaches ,eye pain,swelling,sinus pain

But is it a good idea it stop as I haven't had much burning or grittiness or the usual redness, I can see my tear film evaporating very quick and a patches in my tear film when I blink. Strange thing is though I have been producing tears when I yawn now and didn't before
