My DS2 (19) is on Sertraline for OCD and anxiety (he's also on the autistic spectrum) His dose was recently doubled.
He is generally a tall..6 ft , slim lad but he jumped on the scales today as they happened to be out in the bathroom and he has lost half a stone or so. He can't really afford to lose more as he is built like a whippet!
Is this common? I haven't noticed a decrease in appetite. His diet is a bit odd due to his autism, but not dreadful by any means.
