hi- i have had that exactly for about 18 mos- this symptom can be a sign of depression- and that is what my Dr. said I have due to the IBS and just menopause, difficult job, etc. Have run a daycare from my home for 20 yrs and have reason to be tired, but this is different- felt on the brink of tears all the time because all i wanted to do was lie down and couldn't due to the job I have-have gotten much better with the following remedies-(hate drugs, but when u have to take them there is no other choice-1. Celexa,20 mg once a day for 1 month, just cut bk to 10mg(jittery, shakiness side effect, not sleeping well-) but the extreme exhaustion is gone-2. I take 1/2 scoop of Reliv Classic, Innergize and Fibrestore in a glass of water or cranberry juice, 2xs a day- unbelievable difference- these are balanced vitamins and the fibre is easy to take- Chronic d to water is completely gone- going once a day"normally", urgency and feeling of not evacuating completely are all gone- 3. Take 1 or 2 Caltrate D(the pink Box) each day- I have gone from having chronic IBS, no pain, but 5-6 "rush" attacks a day, even having accidents in my own house when 15 ft. from the bathroom, to none since Dec.30 when startd the celexa(an anti-depressant, similar to Paxil, but with supposedly less side effects- i have a terrible time with drugs, but this has helped- also was taking xanax several mos ago, , 1 every other day or so if felt myself getting really agitated- haven't needed anything since the celexa- the reliv products have all the essential things in a powdered form and i felt the difference in 3 days after starting -if u want to, contact me at my e mail and i will be glad to tell u how to get them-I think it is easy to lose important nutrients with chronic D- i had this severely for 6 wks last march- lost 20 lbs in 4 weeks- couldn't get the D under control and was in a severe panic attack every day- i could hardly stand up(was unconsciously hyperventilating) went to er- even though had d for all that time, all levels in lab work were normal-so it must not be easy for the levels to show any deficincies, but a person can certainly feel like there are- when several tests came bk normal and i realized I was ok, I was able to get some control and problem abated in its' severity-but it took months to feel better as far as energy was concerned- hope this helped u- donnamaria
