I am just the opposite, loose stool all the time for months. I do get BLOATING a lot though & I feel it's from the azithromycin of the big 3. I used to take Azithromycin 250 mgm. 3x week years ago per my lung doc before I found out i had MAC. On those days when I took it, I would immediately fill up with gas/bloating. This is what I do now: when I take the big 3 I also take 2 gas X tabs. Then later, in several hours if still bloated, I take one more.
For me, it really helps. Please check with your doctor, as constipation is awful. I also add fiber like sweet potatoes to my diet frequently.
