Need some advice/remedies to assist me while I am waiting for my doctor's appointment. Also any ideas on what is going on with me.

In a nutshell, I have been suffering poor stool and/or other GI issues for 2 or 3 years running now, and it has to stop. I need some relief and normal biological functioning. I am listing all aspects where my functioning is below par, even if I do not feel that it is pertinent to the situation.

1. Frequent heart burn/acid stomach, at least 1x/14 days.
2. Frequent nausea, at least 1x/week.
3.Trouble staying asleep. Often do what I call “power napping” – Falling asleep quickly, reaching REM quickly, waking up feeling rested and unable to return to sleep, but not fully rested as extremely tired/fatigued 4 or 5 hours later.
4. Frequent trouble getting asleep, 2 or more times per week, currently taking Diphenhydramine.
5. Bowel movements often water, dark. Fiber-rich diet AND fiber therapy required for any kind of consistency. I suspect that I require an inordinate amount of fiber to bulk stool.
6. Fatigue quickly, especially during high stress.
7. Occasional loss of balance, esp. after sleeping or sitting for long periods of time, at least 1x/month.
8. Caffeine aggravates these problems, but eliminating caffeine does not completely resolve situation.
9. Frequent melancholy/depression symptoms.
10. Frequent irritability, at least 1x per week, sometimes with no evident/rational cause.
11. Occasional (1x weekly) aggressive feelings.
12. Loss of interest/motivation.
13. Currently noticing an increase in the frequency and intensity of the nausea, esp. 15 minutes to 2 hours after eating/drinking.
14. Have recently regurgitated food or beverage shortly after eating.
15. Hungry, but no appetite [don’t feel like eating] (though I think this is related to my nausea and not wanting to feel bad).
16. When I do eat, friends/relatives often comment on the size of my appetite and how much I ingest.
