i quit smoking i believe 6 weeks ago

and unfortunately i gained like 9 lbs...this isn't cool cause i was doing a good job losing weight.
i guess i gotta let my body adjust then start losing again or i just need to make some changes to eating habits and start exercising cause this is not cool at all.
😭
is it normal to gain this quick? is that quick? idk..i know i have gained in that past..quitting smoking before but thought it was over time!!!
