I’m not getting enough flavour from my e-liquid

Try the following:

Blow gently through the tank to get the liquid flowing and release flavour.

Take a drink of water to flush your taste buds.

Consider how old your e-liquid is - oxidation can lead to degradation in the flavour of vape juice over time.

Clean your tank and connections to make sure that no grubby build-up is affecting flavour delivery.

Change to a different flavour for a while - if you’ve been vaping the same flavour for a while, you may be suffering from vaper’s tongue (also known as olfactory fatigue, vaper’s fatigue or flavour fatigue). Don’t worry, switching your flavours around periodically usually does the trick.
 

If none of that worked:

Do you currently have a cold? Our sense of taste is hugely affected by our sense of smell, so a cold can often be the culprit of things tasting bland or nasty. Also, stress, certain infections and/or medications can lead to a temporary change or loss of taste.
