TMI but I want to hear if anyone else is going through this or has before!!

I was having extreme nausea, no vomiting but enough to where I couldn't sleep, drive, eat, drink, or stand up without feeling sick and dizzy. I ended up losing over 6lbs in a week so I was prescribed Zofran. A couple of days later I am having excruciating constipation. Called the doctor and tried everything they recommended including fiber supplements, drinking tons of water, suppositories, colace, and even an enema as a last resort. Nothing has worked! I didn't even have any luck with the enema. Going to the doctor tomorrow but I am so scared they will just tell me to keep trying. It's been a week with no BM and I am physically uncomfortable and in a lot of pain. I stopped the Zofran so now I am extremely nauseous and painfully constipated. Any others with any experience?
