This happened to me during my first pregnancy, and started up again a month or two ago. I don't have the desire to eat non-food items (pica) but I REALLY want to smell gasoline/garage fumes. Like it is an overwhelming urge. I don't do it because I know it is horrible for me and the baby, but sometimes even walking past a garage or being stopped at a gas station just makes me want to stop and inhale deeply like it is the smell of baking cookies or something like that! It hasn't been as bad this time. With DS, DH started padlocking the garage because I seriously could not stop myself from sticking my head in and inhaling when I walked by. So crazy, I know. I looked it up when I had it before, and I guess it is a form of pica, but for some reason I want to smell dangerous substances instead of eat them. Anyone else have weird pregnancy symptoms?
