Ouch...4 months is not near enough time to have a change in your life...It is just the beginning...and if they are not helping much then you need to do what the doc says...increase them...I am just increasing mine...and I think they are finally starting to work...I am cleaning the house...someting I haven't felt like doing for a long long time...lol...do it ouch..please at least for six more months...listen to the doc...you can always give up later...but maybe by then you won't want to...(((hugs)))
