Overdose - Scared SWIM could OD

[UnlikleyHedonist]

Swim got some H tonight. swim doesnt inject on herself ever because she knows she cant do it right and has messed up enough that its better to do the alternative methods when there isnt someone to help. So she put a dime anally (supposivly strong black tar herion), then snorted another dime. was feeling good but not as good as swim would like so did a stupid thing and snorted a 5. Much earlier swim also did a dime anally as well. This was swims first time snoting it in awhile and remembers it didnt do much for her. Swim is pretty high right now, swim is afraid she will fall asleep and not wake up. If swim was going to od wouldnt she by now though? What are some warning signs that swim is oding? SWIM isnt a junkie, has sed for days in a row in the past but this was her first time using in about a week. Swim isnt tiny, 5'9 180.
Thanks for any advice guys.
