So True!
My daughter is on it, has controlled the acne, hard to differentiate mood swings from medication & natural in a teenage girl.
I (tried to) work on the basis that she can tell me almost anything and I won't blow my lid immediately.
Didn't always work, but it wasn't a bad plan.
Meant that she could talk to me when she wasn't 100%.
We don't do it often enough, but dinner at the table, cards or board games after goes a long way to teaching them what was normal when we grew up.
Not head burried in an iDevice (he says with 2 computers, iPad & Phone next to him

)
Daz - good to hear you're son's on the other side of it.
Now the other worry starts - teenage boy - no acne....
