help! can't even take the "lowest level" of Holistic horizons?? (1 tsp of Psyllium) (long)

Hi!

I'm new to the board and have a question:
I have been taking 1oz. of aloe juice daily
for the last month or so and had pretty regular (abt. 2x per day)
BMs.
then a week or so ago, I wanted to start the HH program.
I have never done bowelcleansing before.
So i got the pills but "made my own" mass builder out of whole psyllium husk, inulin, spirulina etc (got the 66% by weight of P. right, too)

First, I tried taking 1 tblspoon of the P., but I got consztipated instantly (no BM for almost two days), so I stopped after one dose and waited two days for BM to go back to normal.

Then I took only 1/2 a pill and 1 tsp. of P. 1x per day for 2 days and again i am constipated...I don't get this..
Dr. Gray says you don't need to faste, so i didn't I ate pretty well though, except for some chocolate.
No BMs for 2 days now (except tiny amounts)
I stopped everything of course, but don't know what to do now.
should i just wait or is there anything I can do to get back to regular?

And most importantly: shoould I start over again?
what should I do differnetly??

thank you very very much for any advice,
I'm really desperate!
