I was at my wits end with this "D" thing going on.I went to the docs office and i cried and told him i wanted tis to stop or i was going to get severly depressed being that i was on my way there. He gave me some thing called DOXYCYCLINE 100 MG i took it faithfully and i am better i havent "d-ed" in one week sshhhh dont say it too loud. i dont have a solid stool but semi hard is beter than not. i only go now once a day and i am back to normal. Thankfully and thank God.
