I took amatriptilyn and zopiclone for sleep problems for about a year. I didn't like the side effects although it made me sleep like a log. I have totally weened myself off both over the past couple of months and for the last couple of days I have not taken any prescription drugs. I now feel like I am awake all night and have weird dreams. I have heard that it may take from 15 days to a month for the prescription drugs to leave my system - and until then my sleep will not be good - but should get better with time once the drugs are out of my system. I am not going back on these drugs but bought GABA and 5HTP. Will it do me any good to take GABA and 5HTP while I am withdrawing from the prescription drugs. They are expensive and I don't want to waste money if they will not help over the next few weeks.
