It can do but i shouldnt think by much, just glug extra water today and back on the packs and you might be in K by tomorrow again.
Dont get upset, theres a reason why they are a ex amd there not worth to put weight on over, you were doing great, so just draw a line and get on with it again! hugs babes
Dont worry hunni, drink loads of water and have a great day, dont let the ex upset you shes not worth it, just think when you are all slim and sexy who will be the upset one then hun.lol.
I don't think you'll have put on as long as it was just the once. It could stall your losses for a day or 2 cause the salt may cause water retention. Like the others have said just get to glugging and keep moving forward.
