Call your doctor, if you have a disorder which causes you to be impulsive, TELL your doctor that. He may decide to only prescribe enough pills for you, of any kind, which you will only need for a day or two. This is commonly done with antidepressants and pain meds for people with control issues. Most likely, aside from some nasty constipation, you won't suffer any lasting effects. Make sure you eat some fiber, (not too much, some fruit, or some granola with bran will be helpful) and drink a lot of water. THEN call your doctor. You should be fine. But. please ALL the doctors you see for anything should know you have self control isssues, so you don't harm yourself. Good luck. I hope you feel better.
