What are the side effects of Tizanidine?

Hello doctor,

I started taking 2 mg of Tizanidine today due to severe spasms. I am directed to take one in the morning and two before bed. I was advised to take a total of 6 mg per day. However, I am having the issues of dizziness and lightheadedness, sweating, agitation and anxiousness, super crazy dreams that wake me up, hallucinations (seeing or hearing things) and dry mouth. I am trying to determine how long these side effects will continue or if I need to seek immediate attention. Kindly suggest your expert opinion. Previously, there was nerve damage due to a traumatic C-section where both the uterus and bladder were injured. Both the injured organs were repaired, but I am dealing with sympathetic nerve pain. Currently, I am also on regular Zoloft 50 mg.
