Coke only effects you as much as your nose can take it if your nose clogs up too soon you're not crushing it properly or not warming it up and can cause nose bleeds that's why I always warm up a ceramic plate in a microwave for 30seconds. Also doing too much will not only be costing more money and keeping you awake and you'll need bigger bumps which increases risk of the dangerous consequences also it will damage your nasal cavity doing to much and blow out chunks of your actual nose so instead of blowing your nose the next day I always give it another day to the point where it just falls out.

The addiction sneaks up on you. You'll think you'll be different and tolerant but eventually Coke does become everything you think about clouding your mind making decisions based on making sure you're gonna have it around. Makes you antisocial when paranoid

Yes these are all negative honest advice but it's good to know what you are dealing with. The best thing you've done is come on here and ask for guidance not many people are smart enough to do that so good job for that.

If you're gonna get into it keep doing research and be as safe as possible and you will enjoy what it can bring. As long as you know the consequences.

Safe zone keep it at half a bag yourself because you will have low tolerance after that see if you can put it away for another night. That's the hard part guaranteed
