I always wake lying on my right side and my bed partner says I spend the whole night on my right side. Is this normal or harmful. This is very normal and not harmful. I have tried Temezepam, Ambien. I work odd shifts and MUST sleep unusual hours during some weeks.
Shift work is difficult to work because of the impact on sleep.
Trying to shift the sleep cycle is difficult. Benzodiazepines like you have tried are the usual method. Taking higher doses may help, but continued use will blunt their effectiveness. Several people have tried melatonin with some success. I am only 17 years old and for the last 3 years I have been sleeping for more than 9 hours each night.
