Omeprazole - How can 7 days mess me up so bad?

All of the sources I found here on the internet did not mention any withdrawal symptoms after taking Omeprazole short term. There were withdrawal symptoms after long-term usage ranging from 3 months to 25 years. Depending on what you mean by "still struggling" perhaps the way you are feeling has nothing to do with Omeprazole withdrawal. You should see your doctor (PCP) as soon as possible and hopefully, he/she can help you. If not, they should refer you to the appropriate specialist. Hopefully, they will recommend a gastroenterologist

Hope this helps.
