NICOTINE QUIT GUIDE

Nicotine withdrawal
is easier to handle when you know what may happen next.

When regular nicotine intake stops or drops, the brain and body have to adjust. The experience varies, but cravings and changes in mood, sleep or concentration are common enough that planning for them is useful.

A practical way to start

Recognise the pattern

Common symptoms described by the NHS include cravings, irritability, restlessness, sleep problems, anxiety or low mood, and difficulty concentrating.

Expect the early phase to feel different

NHS guidance says withdrawal can begin within hours after stopping smoking, is often strongest in the first week, especially the first few days, and commonly eases over the following weeks.

Separate a craving from a decision

A craving is a temporary state. Use a short repeatable response such as movement, water, changing location or contacting someone.

Protect routines

Sleep, regular meals, movement and reducing exposure to known triggers can make the adjustment period easier to navigate.

Ask for help when needed

A healthcare professional or quit service can discuss evidence-based treatment options and help if symptoms are difficult or persistent.
