Severe drug induced constipation

[basten]

I take Amitryptiline, Clonazepam, trazadobe and Risperidone. I only ever passed bits of diarrhoea and use colonic irrigation but now nothing is coming out hardly at all. I take 3 x Laxido a day. It's got worse since I started the Amitryptiline. I eat my greens , fibre etc fruit. The bowel consultant wasn't worried and even said perhaps there's nothing in there but I know there is. He discharged me. I am very worried now . Had anyone else had this problem etc
