Yesterday was day 4 of taking Wellbutrin (150) and Zoloft (50), I became very faint sitting down, I was terrified I was going to pass out. It came in waves the rest of the day. It started right after lunch, so it wasn t low blood sugar. It didn t matter what position I was in. I skipped the Wellbutrin this morning and just took the Zoloft, but still experienced lightheadedness. Luckily I m off today and could rest. How long before I feel better? I took Zoloft with success about 10 years ago... So it s less likely its that, right?
