I am taking diazepam for anxiety I've had several major surgeries, but I'm finding I'm taking too much. I know it's silly. Took 15 mg this morn for a visit to doctor and I felt sick afterwards. Not calm at all. Could this make me feel sick? I've been off of it for a while because I was taking pain pills( not together with diazepam) so I am newly back on it. Any advice appreciated. Feeling pretty lousy .
