Had a similiar reaction when i started black strap molasses supp. it told me that there are some real issue(s) going on within the intestines. bacteria , bugs... old shit/mucous placque. i know what you mean as i have a limo biz. fortunately my runs to the airport only take 30 minutes... during that time, i know if i would ever let one rip and had a passenger in the car, i would have never seen that one ever again.
not getting dehydrated is the toughest challenge truck drivers have to deal with... keeping fluid levels up and drinking lots of water is most essential... especially if you want to avoid developing kidney/gall stones.
Hulda Clark suggested 6 drops of Lugol'sIodine first thing in a morning drink to knock out the bacteria that causes gas.
but if the supp indeed works as Humble say it does, you should have knocked out the cause in a couple-three days... you are probably throuh the worst of it by now.
see how it goes in a couple more days.
otherwise, if air continues to be toxic and if you're trucking on long runs that could be real difficult...

leave your son at home and work solo if you can manage until you get through this... be sure to buy your partner and your son plenty of dinners, drinks and whatevers to help them understand that you need to get through this...
p.s. careful with lighting up them cigarettes...lol
