Worth lowering body mass to OD easier on a smaller amount?

[Mistiie]

I'm looking at taking a lethal dose of morphine solution (1 gram should be like 5x the lethal dose, so I'm assuming that's more than enough even when ingesting) and I was wondering if it was worth going on a diet or just downright starving myself so that I could lose some weight to go quicker. I've heard that it gets easier or harder depending on your weight, so is this true? Is it worth losing some weight so that I can have more efficacy out of the solution?
