Currently on 150mg of Well XL, its been pretty effective but still feeling moody and irritable at times. Doc suggested 300mg of XL but after a week trial I was still not adjusted and felt really wound up and had lots of pressure in my head, but my mood was better! Now we are going to try Well SR 200mg/day ( 2x 100mg/ daily) to see if that gives me the little boost I need. Anyone gone from XL to SR to help with a mg increase???
