An idea I just had is to turn the water on and fill the tub really slowly. That way I won't actually be submerged until I'm fully unconscious. Once I die the excess water will go down the overflow drain so I don't need to worry about water damage afterwards
I'm undecided, but after two failed attempts of ODing on valium, grapefruit juice, and booze (first one almost worked because I aspirated but was found... second attempt was ust an uneventful nap...), I'm considering this as well. My bathtub is relatively small, but I have 300 mg of valium on hand plus a full bottle of methocarbamol. I worry that trying to submerge and drown at the moment it begins to kick in will mean that I just flop out 2 seconds before passing out for 10 hours on the bathroom floor, but since my tub has a safety drain, I'm thinking that if i get into the right position and let the tub fill slowly that it'll give my body time to let the valium, alcohol, and methocarbamol work it's way into my system so that by the time my face is submerged I'll be too knocked out for SI to do anything.
I know I've read at least one article saying that a "surprisingly high" number of people die each year from getting drunk and drowning in hot tubs, so add some benzos, muscle relaxants, and actual intent and I'm hoping it's a possibility to consider.
