Nights were hard no doubt about it.
The battlefield is the mind. It is our thoughts and beliefs that determine our mood. Happiness is a choice and must be our goal.
When I was battling my thoughts at night I would spend every night here and then I would always have a book about addiction, codependency or some other relevent topic to keep me on track. Reading makes most people sleepy.
If I could not stop the thoughts I got my laptop out and went back to SR and read some more posts to strengthen my resolve.
Refuse to entertain the thoughts... clear your mind. FORCE yourself to think about something else. It is discipline. It will be hard. It will get easier.
If you have trouble sleeping you should pick up melatonin... it is all natural completely safe and what your body produces to induce sleep. Available at any drug or health food store...
this too shall pass...
