Gastrointestinal pains after taking galantamine+choline?

I've done a lot of reading about lucid dreaming, especially the Thomas Yuschak book. Anyway, I bought a bottle of galantamine+choline from a reputable specialist shop not long ago and took my first pill last night. All was fine and although I didn't get lucid as such, my dreams were much more thorough and I remember them better.

The reason I am posting though is that I have had very bad gastrointestinal pains this morning which started very early and are still there (although not as bad). Obviously it is not definite that this was caused by the pill and could have just been a coincidence but I am wondering if anyone else has experienced this and whether it normally subsides after taking the pill a few times or not?

The pills have 4mg of galantamine and 200mg of choline and I took only one pill.

Thanks.

choline is known to give diarrhea. if it lasts more than a day id be concerned, but not otherwise. drink water and all that.
