There is no normal--there are only those SE that are reported most often in trials. I had no issues with effexor. I had bad side effects with Wellbutrin, but they went away after 10 days or so. I stayed on Cymbalta for about 6 months,and it didn't help, the side effects didn't go away. Two weeks is a standard some doctors use, so she contacted the doctor and made a report of the issue. She is doing her job. Since she is on the loader dose, it will not hurt her to not take the pill if her prescription ends.
I feel as if I ought to mention this--it seems as if your anxiety is driving some of this. How much--I cannot say, since I do not know you, your daughter, or the dynamic. You state that you have anxiety. You say you are not trying to push, but you are. You are making suggestions and worrying and trying to convince her to do things your way. I understand you are worried. I understand there are things in life that need attending to--there always will be. This is not a productive way to deal with your worry. Seriously--I work with young adults. Eventually, she will tell you to take a hike, and cut you out of the process all together. Actually-it sounds as if she is headed this way,since she is not being as communicative with you as you would prefer.
Take a deep breath. Re-read your posts as objectively as you can. Stop focusing all your attention on her. Let her handle it.
