I Am Currently Taking 100mg Of Trazodone 1x At Bedtime.

I am currently taking 100mg of trazodone 1x at bedtime. I also take 10 mg Paxil oral for moderate anxiety disorder and last I take 150 mg of lamictrol 1x at bedtime. I take these meds because Im a recovered opiod addict. My addictions led to all these diff problems w my brain and my mental health. Im clean 15 months but Idid drugs for 32 or more years. My problems are that 1. My feet, legs and my neck are swelling. Its very uncomfortable. My legs and feet/ankles are tight and my skin looks blotchy red and kinda yellowish.I have been hoarse for 8 wks(sometimes no voice at all). Im struggling to exercise or simply do housework or yardwork because Im having trouble breathing. Also my leg and butt muscles feel like they are really tired...like they might fall off. Im a 53 yr old woman and a pack a day smoker. Im really concerned because Ive gained about 50 pounds quickly just since January(5 months). Im worried Im gonna have a heart attack or something equally as awful. Another thing is that Ive been sweating a lot more than ever. I think thats from being fat.. Who knows, please help me.
