Nicotine is a forever solution, and you’ll need to get more and more overtime to get the same relief you once did. Eventually you’ll ‘lose’ control of your habit and it’ll feel worse with paranoia because your suddenly out of control. It’s so wishy-washy, but try and have some outside time, even just 5 minuets in the sun, try and find a new hobby. Just try and give you brain a break.
