Talinka,

Happens to me too. Even though we know its water retention, it doesn't make the gain any less disappointing. I try not to weigh myself during that time.. and I look at it as an opportunity to wear my most comforting clothing and not worry about how I look. Most of all, I don't allow it to interfere with my eating habits. I love the whoosh after it's all over and done with!

Hang in there!
