Increasing 20-30 - support?

hi all to recap i have been on cit second time for 10 weeks (8 on 20). there has been some inprovement but slow and incremental and i am very up and down. my psych wants me to go up to 30 but i am really scared about it as i do t want the side effects back, particularly the increased anxiety and panic and the awful burning sensations. anyone out there with positive stories about increasing? thanks
