No need to worry, ibuprofen is a bit acidic so that's why we were telling you not to take it. I myself take Tylenol for aches and pains. It's easier on the tummy. Metro and Tagamet will actually help your sensitive stomach. My guess is you were going through a bunch of emotions when you thought you were ready and are now experiencing that low low that always comes afterward. Luckily it's followed by a blissful period of not feeling anything. You also will have increased gastrointestinal issues from all this today. It's your body of reacting to the stress. Eat foods you know you aren't sensitive too for the next couple of days.
I'm proud of you for stopping. That takes real courage.
You can always PM me if you need talk.
