I have been taking Singulair for almost a year for asthma. I visited my family physician and he prescribed it for me and also gave me an inhaler. It only helped a little bit. I found out that we had a mold/mildew problem in our house from a water leak. I moved there and having been living in a new place for 5 months. After the 1st couple months, the asthma did not clear up. I went to a allergist and they said it is from acid reflux and not asthma. I have been taking prevacid for a couple months. The breathing problem has starting clearing up. This week my doctor said to stop taking the singulair. I also just started seeing another doctor for my ADHD. This same week he put me on 10mg of adderall 2x a day. So far I have been feeling a lot better and not so depressive and impatient or angry as some put it. I also have been able to get up earlier and not always so tired. I quit my job and am starting a new in a couple days. Also, I put on a little weight & size since taking singulair. My waist and neck size expanded. Maybe I am feeling better maybe because of the new meds and maybe because I stopped singulair and even getting a new job (i hated my other one). The thing I can't figure out is that after i stopped the singulair I had this pressure in my stomache area but it doesn't feel like it is in my stomach (it doesn't have the full feeling). It felt like this for a couple days. 4 days after I stopped it, my stomach area under my sternum swelled up. I could feel it as it was doing it and it bulged out a little. This happened within an hours time. I went to the hospital and they ran test and everything was ok. They said to wait and see what happens or go get a laxitive to release my system because it was just gas. I didn't use the bathroom this day or the next. I took the laxitive. My system cleaned out today but my stomach area still doesn't feel right. Any ideas?
