I have a recipe for a drink that should eliminate (pardon the pun!!!) the need for any laxatives. It's called the Hot Slider.

6 oz prune juice
30 ml Milk of Magnesia or Karo dark corn syrup
2 pats butter

Mix all ingredients into glass, nuke for about 45 seconds depending on your microwave oven, stir, and drink. Doesn't taste terrific, but within an hour or two that stuff'll come "sliding" out of you slicker than grease through a goose. It's what I use to bomb my husband loose when his cancer meds get him all blocked up, and I've only seen it fail a few times.

Try it and let me know if it works for you. In the meantime, cigarettes and coffee probably don't have much of an effect on your meds, except those you'd take to suppress mania. As you may know, these are nervous system stimulants, and if you're trying to avoid becoming manic, they aren't good choices. But you knew that already.
