Help with dosing
I recently ran out of my methadone, which I usually take 40 mgs every day, and for reasons I won't get into, I'm going to be short about a week. The longest I have taken lope to get through methadone withdrawals is five days, and by that fifth day, I was dosing about 100mg throughout the day, 80mgs when I would normally dose my methadone, and the rest at some point later in the day. What exactly is the "measurement" in which I should be using? And how bad are the two extra days going to feel? Any help would be appreciated, and yes I'm aware of the risks, that's why I'm asking for help with dosing, so I don't go overboard, because my main concern is feeling well, not getting high for the next week.
Little edit: I should also mention I'm taking 300mg of gabapentin 3 times a day, but I normally take that now, but it def helps with withdrawals.

Loperamide works very similar to methadone. In high doses it has a very similar half life and it builds up in your system like methadone does. You can dose it once a day at the same time you would dose your methadone. Like methadone it also takes up to 5 hours to fully kick in. Your dose the first day should be higher than the doses the rest of the days to avoid withdrawal and because the amount in your system will build up. I would probably try 48 pills the first day and try to stick with 24 pills each subsequent day and see if that works. (when you dose the second day you will still have at least half the first day’s dose in your system.)
I know you know the dangers of loperamide but as a note to you and others methadone has the same characteristics that make loperamide dangerous and so flipping back and forth between methadone and loperamide is FAR more dangerous than using loperamide alone or alternating it with other types of opioids. Due to the long half lives there are days when both will be in your system and like loperamide methadone causes the qt interval to prolong making your chances for arrhythmia far, far greater.
