Can I safely consume Everclear?

How should I go about drinking this? Id like to try it.

I’ll drink tons of water and only have a few shots over a few hours, but like I’m not sure how to interpret the beast of a drink this would be.

I drink a fifth of whiskey in 2 days if I’m having fun. Or in a week if I’m chilling.

Where do I buy everclear? My local liquor store?
