I'm sorry you are having a nasty flare. I hope the IVSM works for you and you start feeling better soon.

In addition to the mints, lemon drops are good as well. I've also brought lemon water with me to drink. It seems to help with the metallic taste.

Drink plenty of water and other fluids throughout the day(s) to keep hydrated.

For me, IVSM makes me feel really tired and sick feeling. I do not get the energy bursts that others seem to get. Have some books or magazines and other "quiet" things to do at home just in case you get the same reaction.

Zantac is a good idea. It will help with any GI symptoms you may get.

Let us know how it goes and how you are doing.
