My generic Wellbutrin 100 SR generic manufactured by Activas is not working like when I took the brand name 150 mg XL. My insurance will not pay for any brand names. Has anyone found a pharmacy or online pharmacy with a reasonable price for the brand name. I do not trust the Canadian or other Foreign pharmacies. Need a made in the good ole USA brand. I found one and it was over $1,000.00 for the XL brand name... Yiiiikes!! And they have you because you cannot get the 300 mg XL and cut them in half since they are time released.
