Wellbutrin XL

I’ve been on Bupropion XL 150MG for about a month my doctor recently just upped my dose to 300MG are all the side effects gonna be the same thing the only two i’ve really seen is major narcolepsy and constipation but i’m also not getting enough fiber because medication scares me! On top of that i’m on Lamictal 25MG Effxor 150MG and My PCP just put me on Blood Pressure Medication due to my stress and anxiety levels being through the roof and my blood pressure rising to these levels!
