I have been using it for years and it sure does help my fibre intake and my outbound too! I usually have a smoothie to break my fast and psyllium husk is one of the ingredients and if it doesn’t sit too long in the glass then you can barely tell it is in there.
I take it every day at the start and end of my eating window. It has been the secret weapon and my health numbers just came back today at the best they have been in over a decade. My blood sugar was in the pre-diabetic range, but is now at a very low and very healthy range. I think the fiber has so much to do with that. Hopefully that helps motivate you.
As for drinking it - I put it in a dry cup. I add about a cup of water and stir it with a spoon vigorously as quickly as I can, and then I drink it as quickly as I can. Not all of it may come out, so I add a little water again, stir, and drink. I then chase it down with a full glass of water. The secret is to get it down before it starts to gel. You just have to push through it. You get used to it. If not, you can buy the pills, but it is much harder and more expensive to get enough that way.
