Sub oral solution?

[oathrocks]

SWIM is going to be taking a very long, very needed break from opaites. SWIM was told by some friends that one way to make subs last, and to help with WDS is to take a visine bottle, empty it out refill with water, and put 1-2 (up to 4) milligrams of crushed up sub in the bottle and shake. When ever SWIM would be feeling ill he would take a drop or two and put it under his tongue, and repeat untill he feels better. SWIM has a very limted amount of subs and needs to stretch it so this would make a little last alot, and it will keep in the visine bottle for a long time. SWIM is planning to do this and is wondering if anyone ahs ever tryied this before? any thoughts for him?
