After it became bad again recently, and I was getting up in the night a lot - even though I was only doing a tiny bit of wee each time, I decided to research further. I found a research paper online. It was a very small study. The key learning was that women who DON'T suffer from interstitial cystitis have more menthol in their urine than women who do have IC. Menthol is a by product of kidney function I believe. Peppermint is the plant that contains menthol.
Immediately I started to drink peppermint tea which helped somewhat. Then I bought some peppermint oil capsules. Mine are the High Strength 100mg soft gel capsules and I take one in the morning and one before bed. I'm in the UK so I get the brand Nature's Best. Complete gamechanger! I am getting up only once in the night now. Going much less often during the day. Also just less aware of bladder pain. They are not very expensive so perhaps worth a try?
