According to my friend- within a couple of days improvement will be visible. But to be on the safe side he advised me to continue this treatment for the next week or so, twice a day.
To be honest from what I can tell it already receded somewhat. But I will be certain only when I can get someone to help me open her mouth and keep her still. She is insanely tenacious and dexterous. She rotates herself like a spring, so she manages to rotate herself even when in my firm grip- it's either me allowing her to or she breaks her own neck. Insane little thing, she doesn't even do it in panic, it's all very calculated and slow. I really do think that these snakes are a deal more intelligent than others.
