day 2 - in need of some motivation

info: 25FTM, heavy daily smoker

doing my second tolerance break ever (2 weeks minimum) and I have been firmly humbled. Thankfully this time I still have an appetite but these cold sweats are horrible, sleep is hard and I feel very irritable, as well as an all round "bad feeling" . I'm finding it really hard to keep going and would appreciate some anecdotes and experiences for others who've been through this.
