I personally injected too much by mistake once or twice in these past couple of months. Even today, I had trouble figuring out the amount of coke to put in my cup. Usually I dump everything on a plate and really mix it up but I'm at a friends house so kept everything in the bag. Didn't mix it well enough cause the shot I just took I'm sure made me super close to OD or seizing.

I stabilized my breath, ask my friend for a cold towel on the face and chest (vagal nerve) and controlled my breathing but yeah it wasn't enjoyable, definitely too strong.

Idk how some people can go over more than a day of shooting coke, that sounds insane to me, I feel like my heart would just decease lol

Anyways, any trip report to share? If not, stay safe, hydrated and practice harm reduction techniques!!

Edit to add: I also get cross-eyed / double vision and a bit of nausea after a couple hours
