medication related weight gain

I have a terrible case of insomnia and my dr gave me drugs like anti-psychotics for it,i guess because the cause severe drowsiness however they did not work the side effects were awful and thats what brings me here,they made me gain like almost 20 pounds in 3 weeks,im not an overeater,(actually to be honest I eat very little)never really been over weight,and no matter what i seem to try the weight just wont go away! I walk almost 3 miles every morn,I havent been able to keep my old yoga routine up but would like to get back into it.
Could these drugs have permanently slowed my metabolism? any suggestions on what might help get it back on track?or whats going on?has anyone else ever expierenced this?
is there any particular excercise or anything i can do to boost my metabolism?
any suggestions are appriciated im getting desperate.

 

Go back to you doctor and tell him this - putting that much weight on in that short space of time isnt good. There are lots more drugs you could try - maybe even trying to find why you suffer from insominia might help more.

 

Your not gonna believe this but I did go back he took me off the medication.That was like 2 months ago,and no matter how I watch calories and excercise It just dosnt budge.I dont want to use diet drugs but im gettin desperate.
And the reason I have insomnia is I suffer from Post traumatic stress disorder,It a long story that Im not ready to share in a public forum,matter of fact I just recently shared it with my family about 2 months ago,they talked me into telling the DR,which strangely made me feel worse.but im working on that,hopefully in time I will get some sleep,you see my insomnia started at the age of 10 im now 27 and quite tired literally.
but this extra weight stuff has really got me i dont know what to do,the extra weight wouldnt bother me if I was in shape,Which I really was when this happened and I started gaining but its like all fat,and like I said I cant seem to loose it and I cant seem to get my muscle tone back.Someone said it probably really screwed up my metabolism,but I dont know Never had to deal with any of this before.

Thanks for the reply its nice to know someone cares enough to send a message.
Peace,Love&Blessings

 

Have you had your thoroid (sp) checked because an under-active one can make people gain weight and you never know these tablets might have upset the balance and somehow made it stop working!!!!!

I know my mum is on tablets but for mirgranes and she has put on some weight which she hates but there isnt much she can do about it only try and eat a balanced diet, exercise and hope that it might go off again.

If you are still worried about it go and see another doctor, there are so many drugs out there that you can try - i get insominia but i can control mine!!! maybe even learning to control it (which isnt easy) might help a bit, if you want any info on it PM and me and i wil lsee what i can do xxx
