INF Daily found Lindsay Lohan arriving back at her West Hollywood home this afternoon. Word is the fresh outta rehab actress’ friends are worried that Lohan won’t be able to maintain her sobriety. They claim that she has a hard time “staying put” and needs constant stimulation. Hmm… sorta makes us wonder if LiLo really did have a legitimate reason to be taking the A.D.D. drug Adderall.

It sounds like a big part of Lohan’s problem lays in moderation – she can’t do it. Her friends say Lindsay can stay away from the nightlife for a bit, “‘but as soon as she gets a taste of the nightlife and the drama, she usually falls back into old habits fast.’”

We’re pulling for Lindsay…
