I took 5 sennosides and 3/4ths of a bottle of mineral oil to help my constipation. will i be ok? i'm getting kind of scared

Probably: Will be crampy and could get dehydrated if it all hits at once. Drink alot of water and stay close to home. Why are you so constipated ? Is it chronic? See your dr for a work up of this if its a chronic problem.

Yes: Constipation is a bummer! long term prevention is much better than treatment: high fiber diet, plenty of fluids, or even fiber supplement (eg: metamucil). Stool softeners can help (kind of like soap), and then stimulants like senna, mineral oil, or magnesium (milk of magnesia). Rarely an enema is even needed. Go slow, and try not to over shoot your treatment! see your md for persistent symptoms.
