I cannot imagine 2 drops per glass of 35%H2O2 causing much of a detox reaction, but you never know. If I were you I would continue and even increase the amount slowly over a few days.
As for using it daily, I have known people who used small amounts of it daily for years.
I haven't tried the inhalation method method myself, but it seems to me like you're going about it the correct way. I wouldn't use 3% store bought like Bill Monroe suggests. Like you I would dilute 35% food grade to at least 1% for starters at least.
