please reassure your hubby that he is perfectly safe! 1st thing U said he is losing weight? Thats the main thing...the strips are really unimportant but most people try them just to see. The one thing about them is u DONT want them to read dark purple..means U arent drinking enough water. Some people never get above the trace amount yet consistantly lose weight. So in the end tell him to back off from that bagel...LOL
