I generally just try and stay out of the Health Q's section on here. I feel infinitely better since quitting analogs. The first month was awful though. I had really bad flu like symptoms, muscle cramps/spasms, bleeding gums, general exhaustion, and headaches. I got really worried some of these symptoms were from vaping but after some research I could quickly attribute them to quitting smoking and withdrawal. Now I feel great and have none of those issues anymore and I vape about 3-5ml/day. If people are having issues they are concerned about it's up to them to seek medical attention. Getting medical advice from a forum is probably one of the dumbest things anybody could do for themselves. I have no interest in reading a 10 page thread about somebodies issues. I only care about my health issues and when I have a question there are two doctors in my family I call or I go see my physician if I can't get an answer...
