Ive quit smoking - 2 months as of midnight! my question: when am i going to start feeling better emotionally?

and mentally? i feel great physically but am still pretty foggy/ clumsy. losing stuff, breaking stuff, losting stuff - and forgetful. i feel like im drugged - cant sleep very well either. any tips? i was smoking 2 packs per day for 15 years (only 2 packs at the end maybe a year). I need to start operating on a higher level - i allowed myself some down time but i must be coming out of this soon...?
