"PRESCRIBED FOR: Buspirone is indicated for the management of anxiety disorders or for the short-term relief of the symptoms of anxiety. Buspirone is especially effective in persons with generalized anxiety of a limited or moderate degree. It is not very effective in persons with severe anxiety, panic disorders, or obsessive-compulsive disorders."

buspirone (Buspar) - drug class, medical uses, medication side effects, and drug interactions by MedicineNet.com)
My own experience with Buspar included no side effects and no potential for abuse. It appeared to help me 'unwind' before bed and sleep better.
This is NOT medical advice, and NOT a recommendation, everything could be different for you, see your doctor.
