Yes I am. I bought the bottle, took it 3 days, felt bad about it and stopped. Then I was better.
Some people like to do blood test and have a specialist tell them if they’re doing good or not. It has it’s virtues but it’s also costly and takes time.
I just take a supplement, wait a few days and see how I feel. I’ve discovered new ways of feeling weird I never felt before ! If a supplement makes me feel bad or weird in a bad way, it’s out. If I don’t feel any change I may keep it and if I feel better, I definitely do keep it. However, if it feels too good (as in too good to be true) I will reduce it because there’s a chance of overreaching the state of balance and falling on the other side.
