People with Fecal Incontinence: Psyllium Fiber?

I do have a separate post on here regarding nocternal incontinence, I really have no issues during the day, only when asleep, I usually wake too late. I have been taking metamucil w/sugar for years along with loperamide ( anywhere from 2 - 8 tabs/day). This has worked for many years along with azathioprine & antibiotics for any inflammation, in August I began Tremfya, I have not noticed much difference, tho I was hoping it would help out somewhat with the incontinence.
For those of you that use the psyllium whole husk fiber, I am interested in how much and how often you take this daily? Also how you consume it? Do you mix with small amount of water, use applesauce, oatmeal, peanut butter toast? I have seen some of these listed in ways to consume. I am just looking for some ways to get more than an hour or 2 of sleep at a time. Last night I woke up 5 times in a 6 hour period, I have been wearing incontinence underwear to bed for the past 2+ years, with pads inserted so that I don't have to dispose of the underwear each time, I can just replace the pad/liner. As all of you know sleep is very important to all of us, and the lack of it just really sucks, and staying up later than normal in order to be to control my bowel movements is not the answere either. Thanks for any comments and my best to all of you struggling with the same issues.
