I am a 31 year old man with spina bifida & i find the when i go to the restroom in the morning very little urine comes out of me. is that normal?

Spinal Slowdown: This is not unusual in this type of condition since the nerves that control the bladder could be affected. In such a situation the ability to relax the bladder neck muscle effectively in coordination with the contraction of the bladder wall muscle to begin urination may be impaired. As a result the sensation to void could be affected as well as the ability to empty the bladder completely.

Experience teaches: You have lived with this problem 31 years. How long has this problem been occurring? If most of your life, then you have a "neurogenic bladder", common in spina bifida. But if this is new, consider inadequate fluid intake as cause of your problem. Sometimes an over-distended bladder will not relax readily after overnight sleep, perfectly normal.
