I agree with Debaser as Klonopin is not usually prescribed for sleep but used for anxiety and panic attacks. A med that my work for you is Trazadone, but this would be between you and your physician.
Certain drugs weaken the stomach (tricyclic antidepressants such as Elavil, calcium blockers such as Cardizem and Procardia, L-dopa, hyoscyamine, Bentyl, Levsin, narcotics). I hope this bit of info is helpful to you and keep posting. Great question.
