Let's face it, withdrawals are no fun! In addition to withdrawing to the toxic chemicals smoking introduced, there are also many changes going on in your body.
When you smoked, nicotine triggered the release of neurotransmitters in your brain. These neurotransmitters are responsible for good mood. When you quit, it isn't uncommon for your mood to take a nose dive.
This case of the blues is temporary and until it passes, there are a few things you can do:
Exercise as it releases endorphins and these are also conducive to good mood.
Rewarding yourself with something pleasurable. This triggers the same release of neurotransmitters we mentioned.
