I have my 30 year old son at home attempting to detox from excessive use of pill form fentynal. We are trying the Imodium as recommended on this website. What is safe daily dosage, and duration? Also, should I be concerned about excessive sleep (he hadn t slept much in the last 5 days prior to coming here ) . His girlfriend has the same problem; between the 2, it s hard to know the truth, but I think he was off for 3 days, then used again the day before coming here. Are there serious risk factors to detoxing from this ? I ve gotten so much conflicting info. They did attempt detox facility and only stayed 3 or 4 days
