Lindsay Lohan has given up her cocaine habit and has got hooked to something healthier- Vitamin B12 shots.

The ‘Mean Girls’ star apparently took the shots to fight jetlag after returning from London to host a party at Harrah’’s The Pool After Dark in Atlantic City.

“She said she was suffering from jet lag and requested that a doctor be on call to administer B12 shots if needed,” the New York post quoted a source as saying.

The insider added: “Her other demand was two cartons of cigarettes.”

Later, she relaxed in a private cabana with mom Dina and friends.

However, she didn’t like the deejay and referring to Samantha Ronson, said to the crowd “a certain ex-girlfriend” could teach him “what songs to play.”
