It for 4 weeks without problems. I actually began to feel a little better. Then my Psy MD increased it to 40 mg and I'm having trouble with nausea even though I'm eating when I take it. I have a history of having weight loss surgery and it's very difficult for me to take in 350 cal at one time when med is taken. Also the cost of the med is out of the roof!!! How do others afford to take this med? I may have to stop it due to cost alone. I'm on disability and my Medicare pays 415.00 on 30 day supply. Is this the norm?? Any advice or information will be greatly appreciated. Thanks all.
