Agreed with mk.
But it is advised to take whole dose in the morning as it should help increase energy. Not taken at night. By splitting the dose, you may be reducing the effect of it in your system during the day. Why the switch? What was the explanation? Read up on the med and what the company advises. Are you on name brand or generic? There IS A DIFFERENCE!!!!
Taken at night it could affect your sleep.
Read up on other forums and what individuals have found out about using WB.
Usually it's started on 150xr then if needed to 300. Don't get that...but it's a good medicine out of the new ones. And easy to stop of needed. My biggest issue was bad drymouth.
Each med affects different ways, but Weller is not as heavy duty as some like Effexor and Cymbalta. I would ask about the 150's.
