Just wondering if anyone has ever noticed utter exhaustion as a side effect of quitting smoking? I'm 4 weeks out from last surgery, have been resting appropriately, doing PT, basically doing everything I'm supposed to. I went from 2 packs a day to less than 1 cig a day on 9/10, and have been smoke-free since 9/24. No gum, no patch, nada. I have zip stamina. husband thinks it's more related to no nicotine at this point as opposed to the postop period. Anyone gone through this and if so, know of any "quick fixes" (besides taking up smoking, LOL)? Tx.
