How long till it's out of your system?

Good question. I cannot seem to find this information out either. My daughter did great for the first 2 1/2 weeks, but now her mood swings seem worse. Any more improvements for you since your posing.

My son's off for 4 weeks now. There have been some major changes. His frequent headaches have disappeared, he's not as moody, and he seems to sleep better. The first week off, his mood swings were horrible, but that seem to be tappering off. He's still moody off and on, seems like it lasts a day and then he'll be fine again. He seems to actually be more amimated, just alot more lively which I didn't expect. Always has been very "slow", if thats the right term.(He's very bright, but always seemed to be physically slower, walks slow, last one to be anywhere) Now he just seems full of energy. It's a bit of a shock. He's a chatterbox now, like his older sister. I just thought it was a girl/boy difference. And he's dropped weight. I didn't expect miracles going off singulair, but that's alot of changes.
