Ive been on 75mg Ven for 12 days, my doctor today suggests i go up to 150mg now.

Im a bit worried to do so, because ive only just settled on 75mg?
Im worried about more side effects etc, and i may be ok on just 75mg anyway? what are the advantages of upping the dose?
whats everyones thoughts? and also how long did other people wait before jumping up to 150mg? Thanks
