Be very careful, hyoscyamine is just the pure more active isomer of atropine which can be dangerous and unpleasant.
Read up, get a trip sitter, or better yet get an actual psychedelic and not a deliriant.
I think it is kinda normal for a curious person with experimental tendencis to have to learn over time to deal with having drugs in the house with novelty value but this can make for very irrational intentions - potentially problematic when the drugs are not particularly safe. Wise up, having hyoscyamine tablets might be sort of special or uncommon but that does not warrant its use. Put it in your collection and put some effort in acquiring drugs that can be used responsibly much more easily.
I can tell you I am very happy that I have learned to leave some drugs be, even if they are in my home.
