My friend,
I am sorry to hear that you are in such suffering that you wanna leave, in such a hurry,
But I am concerned about that rush. Rushed plans will always fail, and this will be no different.
To begin with, you mention you are drunk, this is already bad: fasting is important, it clears your stomach and reduces the chances of puking. A body poisoned with alcohol I bet will have a harder time controlling that desire to puke.
To the bare minium, you should have 8 hours of pure fasting, perhaps only with a lil bit of water if you are too thirsty. Also, your dose of SN is absurd: you may think why not go for an overkill, but excessive ammounts of SN will be actually counterproductive: radically increasing the chances of puking. Furthermore, it's just gonna be inedible, I assure you, you ain't gonna swallow so much SN on water, no matter how much you try. Typical amounts of SN go for 20 to 30 grams.
Beyond this, the only chemical you do need is SN, yes, but anti-emetics are nigh-essential. They reduce the chances of puking drastically, and thus increase the chances of success.
My friend, stop. You are rushing things up. This is your most important plan that you shall ever commit to in your life. Do make it count.
