Hey there.
What you have described are of some of the common side effects associated with Zyprexa. In some cases as already mentioned they could reduce in their intensity over time as your body adjusts to this med. However, as already stated it would be a good idea to report all untoward effects to your pharmacist/doctor so that further action may be taken if necessary. I'm also wondering if you're on any other meds as there could be a possible drug interaction going on here. Again, another thing for your medical team to possibly look into.
