I am really frustrated, I started with immodium and I feel my tolerance has gone up so i need to take more and more, then levsin and buspar and now i'm taking lexapro and lomotil. i feel i need something better for my anxiety, lexapro isn't cutting it and i've been on lomotil for almost a month and i take 2 pills a day and i have had some d still with that. i'm really frustrated and wondering what else i could do to help myself
