I suffer from IBS and headaches. The IBS started voer 20 years ago when I was in my teens. The tension headaches not until mid-20s. Migraines in mid-30s (Oh - I never noticed that pattern before!!). The migraines though are more related to low blood sugar than stress - I only get them when I haven't eaten, usually late afternoon or early evening.anyway, I did go on a two week course of anti-depressants to break the cycle of tension headaches. This was about 7 years ago now. Before that I would get tehm almost daily and they were really bad. Even on good days, I almost always had a low grade one. The two weeks did it - it was elavil, a rather mild anti-depressant I think. I still get headaches but nothing like that. I no longer need Fiorcet to deal with either, execedrin at the worst.I also beleive my IBS is stress triggered. I've been using the hypno tapes to help with that and so far so good. I've avoided the medication route because of worrying about side effects and my personal aversion to being on anything as a daily medication. On the other hand, if this is what will work for your duaghter and will make her life better, then you should definitely check out this route. My personal opinion though is to treat the IBS with the drugs and not necessairly the depression, especially if it as you say because of the IBS. That way hopefully you're going to the root of the problem - IBS can be a very difficult condition to live with and that's not easy to deal with emotionally.All of this is of course my opinions and experience. I really wish you and your daughter all the best. nancy
