Headaches – If you do get a painful headache, then a possibility is that you have taken in too much nicotine. If this happens, simply relax, put down your e-cig and drink plenty of water. Then, the next time you are ready to vape, try using lower nicotine strength e-liquid, or otherwise, don’t vape quite so much.
The other reason you might experience headaches is if you are giving up cigarettes, when you quit smoking, your brain oxygen and chemical levels change. Some of the possible effects are temporary sleep disruption, increased caffeine levels and changes in your diet. All of these result in headaches, but in most cases, you will feel better after a few days.
Sore / Dry Throat or Nose – This side effect can be related to Propylene Glycol (PG). PG is a humectant, meaning it absorbs moisture, and can therefore leave your throat dry or sore. Usually, this side effect subsides within a few weeks, mainly because your throat is adjusting from your usual smoke to vapour. If you have this problem, then, once again, try to drink more water, and if it becomes very painful, please visit your doctor straight away.
Muscle Aches – Propylene Glycol is converted into lactic acid in your body, which can cause muscle aches. Always drink plenty of water to get rid of the excess lactic acid.
Remember e-cigs are not necessarily a health alternative, nicotine is highly addictive and the long term effect of inhaling Propylene Glycol are still unknown,
