I personally use a program called Neuro-Programmer, it might be a tad expensive for some but worth it I think. It's like 90 bucks. It comes packed with sessions to help users deal with anything from addiction to studying. There are tons of sessions to choose from, all of which you can edit. Just under the meditation list alone, there are over 40 tracks to use. Everything from a 10-15min relaxation break to hour long deep theta and delta sessions. Here are the sessions folders broken down (Keep in mind each session has at least 10 tracks in them) - Addiction, Anxiety, Athletic Performance, Cognition - Attention, Energy - Motivation, General Brainwaves, Headaches-Migraines, Healing - Well being, Meditation - Relaxation, Mood, Self-Programming, Sleep-Insomnia, Studying - Learning.
