Question please

been on wellbutrin 450 for around a year, provigil just three weeks. Exhausted after 2 weeks on provigil. Stopped provigil and felt ill still, nauseous and exhausted. Decided to taper off wellbutrin as well over 2 weeks. Still feel terrible. Been off wellbutrin only around 5 days now.
Feel nauseous and sleep much still. Usually get this every January really bad for around 4 weeks. Almost feeling as bad as I do in January. Feeling bad since oct. 15

All started week after addition of provigil and effexor [[only took 6 days]].

Does wellbutrin usually have withdrawal effects. Have stopped it before without any problems.

Does anyone experience nausea with depression. My docs have never seen it they say....gets bad in cycles throughout the year.

My brain can't seem to write this any less confusing...sorry, have tried.

Thank you for any input
