Hiya Joyce -
thank you for your diligent and most informative replies! I will re-read them a couple of times, here are my first comments:
Constipation is indeed a side effect of SSRIs, not for all people though. I myself had irritable bowel syndrome (IBD) prior to my medication. That stopped immediately when I began to take it, and I thank God for that. My intestines made an awful lot of noise, due to the relocation of air. I really had trouble with attending lectures, or going to a cinema, such was the sound. Now I know that IBD can occur in severe stress, as does diarrhoea. There is more to the story, though. There are indications that bacteria can pass the gut lining, and cause an immune reaction outside it; the immune reaction in turn may 'infect the brain' (so-called interleukins pass the blood-brain-barrier) and actually damage certain brain areas that are dysfunctional in OCD. The situation is also called: 'leaky gut syndrome'.
This may sound exotic at first. But it absolutely explains things as I experienced them, in the exact time frame (before and after medication, I mean).
I am very glad that you can handle the use of benzodiazepines. I was given oxazepam (is like valium) for 12 years. It was the treatment of choice for OCD at the time, which I find strange. For me benzodiazepines were highly addictive. I still recall vividly the withdrawal symptoms when I had run out of them (e.g. during weekends).
Your dads youngest sister clearly had OCD, in several ways. What you describe about the events on TV is called: 'thought-action-fusion', it means: the patient cannot really discern the separate entities of his/her thought, and what happens in outside reality. It is a form of magical thinking. I know of a young girl who actually thought that she was responsible for the attacks of 9/11, just by thinking beforehand of something similar. That must have been awful for the child.
That's it for the moment, Joyce. If I think of more I will respond here again.
Cheers, Cuthbert!
