Anal Itching Is Becoming Unbearable After Drinking (admitted Drinking Problem).

Anal itching is becoming unbearable after drinking (admitted drinking problem). Sometimes I use a toothbrush or one of those personal pleasure finger brush things...the personal pleasure thing seems the get further in and relieve more itching but the itch and pain seems to be further and further inside. I try to use Prep H as well while "scratching"
