a) have you tried ginger? my mother has diabetes and kidney disease- she says wonderful things about ginger snaps. (and other forms of ginger, but i can't stomach them at all so i have no idea what they are)

b) if you can find it- coca tea- http://en.wikipedia.org/wiki/Coca_tea is brewed from the same leaves as cocaine but for medicinal purposes, mainly stomach issues. this one i can personally vouch for (altitude sickness in Cusco led to 24+ hours worshiping at the porcelain throne until i finally agreed to the tea- up and about within an hour)

c) i wish you the very best luck in finding the best combination of meds for you- i am a psychologist by training. for some of the issues, try altering your foods and vitamin intake; walking in the sun (possibly even getting a sun lamp considering the amount of sun in the bay area); and exercise- i understand you're tired and not up to it often (see A) but the benefits are amazing.
