My friend used Studd's gel and Utrogestan regime for about 6 months and felt great at first and then worse each month so she had to stop. He seemed to think that upping the dose was the key but she continued to get worse and she cut down before she stopped but may not have stayed at the lower (or higher) level for long enough to feel it. If you do take a break you may have withdrawal symptoms so don't assume that's how you'd be on lower or no dose once levels had evened out, but if you lower it a little and see how the month goes it might be subtle enough not to throw you out too much to make an assessment if need more or less.
In terms of your life situation, do remember that you are the most important person in the world and maybe start there...
