I served in Vietnam in 1966 and 1967. I was medically discharged in 1968 for medical problems related to being shot. When I returned home I had a hard time adjusting to being back in society. I had flashbacks and nightmares. In 1988 I went back to Vietnam as a tourist. I thought I would go one time and then go back home and resume my life. But the trip had such a strong effect on me I joined up with a group from VVA who helped arrange trips back for other vets. By 1992 I was living and working in Vietnam as an English teacher and doing other jobs related to English. At the time Vietnam was just starting to open up ton the West and English was an important skill needed for business and education.
Going back helped me deal with my PTSD by replacing all my bad memories of the war with my new experiences that were much more positive. The nightmares and flashbacks stopped and for the first time in 20 years I wasn't afraid to go to sleep.
I would like to share my experiences with anyone interested. I'm not saying going back to Vietnam is the answer for everyone but it sure helped me.
