How bad are they about evaps? the first few I took were white as a sheet even after they dried... but these last few have very noticeable faint colored lines. then today I took two that I saw nothing a faint something on while they were wet and i forgot about them. two hours later, there were totally lines on them. I've counted myself out for the month so i'm not getting my hopes up, just want to know if anyone else has had this experience with this brand so I know not to get them again in the future.
