You should be straight with your doc and let him know what you're on. Assuming he knows what he's talking about, he would be the best one to talk to about interactions. If you have an infection, getting better should be your priority IMO.
But when you disarm them, you at once offend them by showing that you distrust them, either for cowardice or for want of loyalty, and either of these opinions breeds hatred against you.
I would probably just stop the M1T cycle, but I would not assume you are going to kill your liver, but how long would he have you on?
If you need it to get better, it may be wise to just bite the bullet. Some people with skin rashes, just live through it for the 1-2 weeks it takes to heal naturally anyway, but a respiratory infection is alot more serious.
