Hello, I've been using The Safe Cig for 2 weeks now, it works great, but I've been feeling really funky and don't know whether to blame it or maybe I'm having other problems. I have the 11MG carts and take around 8-10 puffs every hour or so. I don't have any reaction right away after I puff, it comes later and builds as the day goes on. Been having trouble focusing and thinking straight. It gets pretty bad and I'm having trouble functioning. Do you suppose there's something in the cart that's not agreeing with me? Has anyone else had this problem? I would appreciate any input and advice.
