I ve been making a lot of errors at work recently. I ve been forgetful, too. I find it difficult lately to get my point across to someone when I m speaking. Then, when they begin to speak - I have difficulty remembering what they say. I ve been on Zoloft for close to 20 years, Effexor for about 10, and Adderall for about 4. Zoloft - 150 mg daily, Effexor 75 mg, Adderall 5 mg 2 x a day. Just wondering if my symptoms could be tied to medications or something physical. I also take Zocor 20 mg day.
