I am experiencing it right now. In a nutshell, as I was beginning to wean from Cymbalta (too quickly), I had withdrawal effects and my doctor had me add in 10mg of Celexa. About 10 days later she had me increase to 20 mg of Celexa. Then everything fell apart emotionally for me. Sunday, cried all day with the gut-wrenching grief you feel when a loved one dies. I couldn't stop. The 4 days since then I've had anxiety that I cannot stand. I don't even feel like I'm in my right mind, I don't feel like me. My heart rate is fast, my heart pounds, I'm sweating and shaking, I have no appetite, and periodically my leg just jerks.
I found out the Omeprazole I was taking (for reducing stomach acid) ALSO reacts with Celexa and increases it in your bloodstream. I stopped the Celexa yesteray, and the Omeprazole today.
The doctor prescribed 0.5mg of Lorazepam to take 2 times a day if needed. Yesterday afternoon I took it and for the first time in days it really helped. I felt back to myself.
This morning I was scared to wake up to all the anxiety symptoms again. I took a Lorazepam and it let me sleep for about 1 hr, but I feel no relief from the other symptoms. The anxiety, I cannot handle this. I am wondering if I need to go to the hospital. I feel like I'm losing control.
